[clr-interp] Set up fully interpreted functional test on iOS and MacCatalyst

[kotlarmilos]

Description

Update the build to bundle the CoreCLR static runtime and interpreter for Apple mobile. Set up a functional test to run the "Hello World" sample in full interpreter mode, and verify that the app completes without failures.

iOS Simulator

• Update the build system to statically link the CoreCLR runtime and interpreter without JIT
• Implement missing Interlocked_Exchange intrinsics for i4/i8
• Fix Checked configuration -- the interpreter-to-native stub is null; if generated explicitly, the target function is null
• Fix overridden P/Invokes -- they are compiled as normal calls and the IL stub is generated instead of native call stub

MacCatalyst/ iOS

• Updated the build system to statically link the CoreCLR runtime and interpreter without JIT
• Test fully interpreted app
