Add msstore productId to export manifest and to wingetutil interop ma…

…nifest object (#4934)

This change was needed as part of the effort to make exported manifest
(from winget download msstore apps) to be re-parsed and uploaded to
winget rest source.
 
Updated the some of the manifest schemas to add "required" for some
required fields previously missing.

Also, during my cross validation with the manifest schemas, I found
ExpectedReturnCode::Custom was added in manifest but not actually
updated in code. So I updated the ExpectedReturnCode map in code with
this change too.

Remove attribute in DSC (#4932)

## Change
Removes the attribute `ValidateNotNullOrWhiteSpace` as it is only
available starting in 7.4. The attributes also only validate when the
value is assigned, so enforcing that a value is set is more complete.

## Validation
Loads in PS 7.2.8 now.

Add support for 1.9 manifest in rest source parsing and winget utils …

…interop (#4906)

Revert ARP error change and AddOrUpdate return bool in 1.9 (#4895)

Add extended error codes to results without them (#4858)

## Change
Adds `HRESULT ExtendedErrorCode{ get; };` to the `FindPackagesResult`
and `ConnectResult` classes that did not have them. They work just like
the other cases, exposing the raw `HRESULT` value from their respective
operations.

Generate test certificates in pipeline (#4747)

The tests use test certificates for codesigning and for HTTPS with the
localhost server. These test certificates were stored as secure files in
the pipelines.

This PR changes the test pipeline to generate the certificates on each
run so that we don't need to create new certificates when they expire,
or if we want to recreate the pipelines in a different ADO account.

* Added pipeline steps to create/install the test certificates for
codesigning and HTTPS. The scripts export the path and password (a GUID)
as pipeline variables for use in subsequent tasks
* Removed unnecessary BinSkim task (already included in official
pipelines)
* Removed unused certificates from the code (unrelated to the ones being
replaced)
* Updated hash tests that were using the existing certificates to use a
different file, as the cert is no longer constant
* Added collection of the logs from the localhost server and index
creation; this requires stopping the server after it is used
