Fix resolving node modules directory with custom exports

[fortmarek]

Summary:

Fixes #1168

As described in the issue, it's currently not possible to use RN CLI with packages that have exports in their package.json and do not contain package.json itself in the exports object. For example, d3 dependency does just that. While maintainers could make their package compatible with the RN CLI, such an effort would be huge and not all maintainers want to do that – understandably so, especially if their packages are not exclusively for RN.

To fix this, I've imported this method from the @rnx-kit/tools-node package that does not depend on the require.resolve method (which currently does not work in the case described above). Alternatively, we could just import the method itself but the package is quite small, so in this case, it's probably better in the long run to depend on it instead.

Test Plan:

• Clone this sample
• cd into it and run yarn
• Run yarn start
• Observe error similar to:

error Failed to load configuration of your project.

• Clone the branch from this PR
• Set up CLI as per these instructions
• Once the custom CLI is linked inside the repro sample, run yarn start again
• No error should occur

Thanks! I decided to vendor the implementation of pickValues and findPackageDependencyDir due to the @rnx-kit/tools-node package adding roughly 42kB: https://packagephobia.com/result?p=%40rnx-kit%2Ftools-node. RN CLI already downloads a lot of stuff and we need to make a better job at keeping it lean so that npx react-native init speed is good enough.
