ARM64 Release build failure in WebRtcInterop.UnitTests linker

[General-Fault]

Problem

Building WebRtcInterop.UnitTests for ARM64|Release currently fails at link time with unresolved symbols from Google Test (including missing main and parameterized test registration symbols).

Observed behavior

When running all-platform compile/test validation, the ARM64 Release build of WebRtcInterop.UnitTests.vcxproj fails with many linker errors (LNK2001/LNK2019/LNK1120), and no ARM64 unit-test executable is produced.

Repro

1. Build WebRtcInterop.UnitTests\WebRtcInterop.UnitTests.vcxproj with:
   • Configuration=Release
   • Platform=ARM64
2. Observe linker unresolved externals from Google Test and missing entry point.

Notes

• Managed unit tests pass.
• x64 interop unit tests pass.
• This issue tracks the ARM64 Release interop unit-test linker failure independently from current project-file cleanup changes.
