[ci-scan] Skip HugeArray1 R2R compilation on x86 (refs #128531)

[github-actions]

Reasoning

Crossgen2 consistently crashes with System.OutOfMemoryException when R2R-compiling HugeArray1.dll on windows x86 (32-bit). The OOM occurs in ObjectWriter.EmitChecksums when allocating a large array. This is inherent to x86's limited address space for this very large test assembly.

The CrossGenTest property set to false for x86 is the established pattern — sibling test hugeexpr1.csproj uses the same approach for the same reason (dotnet#74555).

Linked KBE: dotnet#128531

Match verification (from Step 4.8):

1. Same test/family: yes — HugeArray1.dll in jit64_3 work item
2. Same failure signature: yes — System.OutOfMemoryException in ObjectWriter.EmitChecksums + exitcode -1073740791
3. Same OS: yes — windows
4. Same architecture: yes — x86

Impact on platforms
