Marks all Dart-wrapped Android native classes as `@immutable`. They are all immutable anyway because they extend `JavaObject` which is immutable, but marking them as immutable explicitly avoids lint warnings caused by [`must_be_immutable`](https://dart.dev/tools/diagnostic-messages#must_be_immutable) when generated mocks of these classes are used (see dart-lang/mockito#200).

Also, updates `CONTRIBUTING.md` to include marking wrapped classes as immutable and extending `JavaObject` as requirements for adding new wrapped classes.

cc @ChristianEdwardPadilla: this should fix the internal lint errors caused by `JavaObject` being immutable.

Adds scripts and LUCI targets for the Linux desktop platform test tasks, corresponding to the Cirrus linux-platform_test tasks.

Part of flutter/flutter#114373

This moves Android unit tests from Cirrus to LUCI. In order to accomplish this:
- Switches the Android LUCI bots from JDK 11 to JDK 12, to resolve a crash when compiling `camera_android` unit tests with 11.
- Adds wrappers to SDK checks where necessary for testability, since the hack to override `Build.VERSION.SDK_INT` in unit tests (which was already giving warnings when run with JDK 11) no longer works at all in JDK 12.

Part of flutter/flutter#114373

<h1>CodeQL Action Changelog</h1>
<h2>[UNRELEASED]</h2>
<p>No user facing changes.</p>
<p>See the <a href="https://github.com/github/codeql-action/releases">releases page</a> for the relevant changes to the CodeQL CLI and language packs.</p>
<h2>2.20.4 - 14 Jul 2023</h2>
<ul>
<li>This is the last release of the Action that supports CodeQL CLI versions 2.8.5 to 2.9.3. These versions of the CodeQL CLI were deprecated on June 20, 2023 alongside GitHub Enterprise Server 3.5 and will not be supported by the next release of the CodeQL Action (2.21.0).
<ul>
<li>If you are using one of these versions, please update to CodeQL CLI version 2.9.4 or later. For instance, if you have specified a custom version of the CLI using the 'tools' input to the 'init' Action, you can remove this input to use the default version.</li>
<li>Alternatively, if you want to continue using a version of the CodeQL CLI between 2.8.5 and 2.9.3, you can replace 'github/codeql-action/<em><a href="https://github.com/v2"><code>@�v2</code></a>' by 'github/codeql-action/</em><a href="https://github.com/v2"><code>@�v2</code></a>.20.4' in your code scanning workflow to ensure you continue using this version of the CodeQL Action.</li>
</ul>
</li>
<li>We are rolling out a feature in July 2023 that will slightly reduce the default amount of RAM used for query execution, in proportion to the runner's total memory. This will help to avoid out-of-memory failures on larger runners. <a href="https://redirect.github.com/github/codeql-action/pull/1760">#1760</a></li>
<li>Update default CodeQL bundle version to 2.14.0. <a href="https://redirect.github.com/github/codeql-action/pull/1762">#1762</a></li>
</ul>
<h2>2.20.3 - 06 Jul 2023</h2>
<ul>
<li>Update default CodeQL bundle version to 2.13.5. <a href="https://redirect.github.com/github/codeql-action/pull/1743">#1743</a></li>
</ul>
<h2>2.20.2 - 03 Jul 2023</h2>
<p>No user facing changes.</p>
<h2>2.20.1 - 21 Jun 2023</h2>
<ul>
<li>Update default CodeQL bundle version to 2.13.4. <a href="https://redirect.github.com/github/codeql-action/pull/1721">#1721</a></li>
<li>Experimental: add a new <code>resolve-environment</code> action which attempts to infer a configuration for the build environment that is required to build a given project. Do not use this in production as it is part of an internal experiment and subject to change at any time.</li>
</ul>
<h2>2.20.0 - 13 Jun 2023</h2>
<ul>
<li>Bump the version of the Action to 2.20.0. This ensures that users who received a Dependabot upgrade to <a href="https://github.com/github/codeql-action/commit/cdcdbb579706841c47f7063dda365e292e5cad7a"><code>cdcdbb5</code></a>, which was mistakenly marked as Action version 2.13.4, continue to receive updates to the CodeQL Action. Full details in <a href="https://redirect.github.com/github/codeql-action/pull/1729">#1729</a></li>
</ul>
<h2>2.3.6 - 01 Jun 2023</h2>
<ul>
<li>Update default CodeQL bundle version to 2.13.3. <a href="https://redirect.github.com/github/codeql-action/pull/1698">#1698</a></li>
</ul>
<h2>2.3.5 - 25 May 2023</h2>
<ul>
<li>Allow invalid URIs to be used as values to <code>artifactLocation.uri</code> properties. This reverses a change from <a href="https://redirect.github.com/github/codeql-action/pull/1668">#1668</a> that inadvertently led to stricter validation of some URI values. <a href="https://redirect.github.com/github/codeql-action/pull/1705">#1705</a></li>
<li>Gracefully handle invalid URIs when fingerprinting. <a href="https://redirect.github.com/github/codeql-action/pull/1694">#1694</a></li>
</ul>
<h2>2.3.4 - 24 May 2023</h2>
<ul>
<li>Updated the SARIF 2.1.0 JSON schema file to the latest from <a href="https://github.com/oasis-tcs/sarif-spec/blob/123e95847b13fbdd4cbe2120fa5e33355d4a042b/Schemata/sarif-schema-2.1.0.json">oasis-tcs/sarif-spec</a>. <a href="https://redirect.github.com/github/codeql-action/pull/1668">#1668</a></li>
<li>We are rolling out a feature in May 2023 that will disable Python dependency installation for new users of the CodeQL Action. This improves the speed of analysis while having only a very minor impact on results. <a href="https://redirect.github.com/github/codeql-action/pull/1676">#1676</a></li>
<li>We are improving the way that <a href="https://github.com/github/codeql-action/releases">CodeQL bundles</a> are tagged to make it possible to easily identify bundles by their CodeQL semantic version. <a href="https://redirect.github.com/github/codeql-action/pull/1682">#1682</a>
<ul>
<li>As of CodeQL CLI 2.13.4, CodeQL bundles will be tagged using semantic versions, for example <code>codeql-bundle-v2.13.4</code>, instead of timestamps, like <code>codeql-bundle-20230615</code>.</li>
<li>This change does not affect the majority of workflows, and we will not be changing tags for existing bundle releases.</li>
<li>Some workflows with custom logic that depends on the specific format of the CodeQL bundle tag may need to be updated. For example, if your workflow matches CodeQL bundle tag names against a <code>codeql-bundle-yyyymmdd</code> pattern, you should update it to also recognize <code>codeql-bundle-vx.y.z</code> tags.</li>
</ul>
</li>
</ul>
