This MR introduces an initial implementation for `ReadPackageFromStream` in order to be able to decompress/read OPC packages, and enumerate their parts.
This is required for supporting AppX packages, which themselves are OPC packages as well. As such, the code does not implement support for reading relationships or interleaved archives, as AppX does not support either (`APPX_E_RELATIONSHIPS_NOT_ALLOWED`, `APPX_E_INTERLEAVING_NOT_ALLOWED`).
-- v3: opcservices: Implement IOpcPart::GetContentType for opened packages. opcservices: Implement IOpcPart::GetContentStream for opened packages. opcservices: Create IOpcPart objects for ZIP entries in an opened package. opcservices: Write the correct compression-related fields while adding files to a ZIP archive. opcservices: Add stubs for ReadPackageFromStream. opcservices/tests: Add tests for ReadPackageFromStream.

Well again, what's the actual use case for this? Is there any
developer who distributes .appx archives directly? On the winget community repository, there are a lot of packages distributed as msix/appx: https://github.com/search?q=repo%3Amicrosoft%2Fwinget-pkgs+%22InstallerType%... Winget also officially [supports installing apps from the Windows Store](https://learn.microsoft.com/en-us/windows/package-manager/winget/source), which requires appx support as well. Outside of winget, there are projects that also release Windows builds as an appx package. Kiwi comes to mind, it recommends that users use the appx: https://github.com/kiwix/kiwix-js-pwa/releases/tag/v3.7.1
I have rewritten `compress.c` to use the `IOpcPartSet` and `IOpcPart` implementations in `package.c`. The current code decompresses all ZIP entries at once, I'll add support for `OPC_CACHE_ON_ACCESS` and `OPC_VALIDATE_ON_LOAD` in future MRs.
v2:
* Rewrite decompression code to use existing IOpcPart/IOpcPartSet implementations.
This will need some cleanup, I resubmitted first patch with !8856.
