Disable large alloc tests on 32b targets

[dhartglassMSFT]

Large allocation tests that fail sporadically on 32b processes. I'm extending the existing disable to cover X86 as well.

Prior to #123248 these were disabled on windows x86 (see old src/tests/baseservices/issues.targets), but that refactor erroneously dropped that.

fixes #127128

Pull request overview

This PR updates a JIT regression test to be consistently skipped on 32-bit processes (and Apple mobile) due to unreliable large contiguous allocations, restoring/strengthening the intended disablement after earlier exclusion refactoring.

Changes:

• Add an ActiveIssue skip in test.il for PlatformDetection.Is32BitProcess.
• Update test.cs to skip on Is32BitProcess (instead of IsArmProcess) and also skip on IsAppleMobile.

Thanks

The wording in that one was probably better. I matched the wording and phrasing here. I added you as a reviewer on this.
