Pull request overview

This PR updates the Browser WASM CoreCLR managed-to-native generation + link pipeline to honor InvariantGlobalization=true by excluding libSystem.Globalization.Native P/Invokes from the generated table and conditionally omitting the corresponding globalization/ICU static libraries from the link step.

Changes:

• Extend the CoreCLR PInvokeTableGenerator pipeline to accept an “ignored modules” list and filter those modules out of the generated P/Invoke table.
• Update BrowserWasmApp.CoreCLR.targets to (a) stop allowing libSystem.Globalization.Native when InvariantGlobalization=true and (b) stop linking libSystem.Globalization.Native.a and ICU archives in that mode.
• Add a CoreCLR-only WASM build test asserting GlobalizationNative_* entries and ICU/globalization archives are absent under invariant globalization.
