[ci-scan] Skip SpanDestinationFunctions_ValueRange on iOS (refs #129045)

[github-actions]

Reasoning

The SpanDestinationFunctions_ValueRange tests in DoubleGenericTensorPrimitives and SingleGenericTensorPrimitives fail on iossimulator-arm64 because the vectorized Tan implementation produces values with reduced precision compared to the scalar reference on this platform. The [ActiveIssue] attribute with PlatformDetection.IsiOS is the narrowest practical scope since the precision mismatch is platform-level and affects the Theory's multiple MemberData cases.

Linked KBE: #129045

Match verification (from Step 4.8):

1. Same test/family: yes - SpanDestinationFunctions_ValueRange is the failing test method
2. Same failure signature: yes - Assert.All() Failure with Values differ for Tan on iOS
3. Same OS: yes - iossimulator (iOS)
4. Same architecture: yes - arm64

Impact on platforms

• runtime-extra-platforms (def 154) / iossimulator-arm64 Release AllSubsets_CoreCLR / Helix queue: ubuntu.2204.armarch.open.ios / exit code 1
