Pull Request Overview
This PR implements the RhpNewArrayFastAlign8 function for WASM and CoreCLR, resolving issue #120659. The implementation enables aligned memory allocation for arrays that require 8-byte alignment, particularly for long and double arrays on 32-bit platforms.
Key changes:
- Implements the
RhpNewArrayFastAlign8function with proper alignment logic - Refactors existing allocation code to improve maintainability
- Removes WASM-specific test exclusions that are no longer needed

Overall, LGTM. I'm like to try and remove some of the "magic" numbers in NewArrayFastAlign8Core. There must be some simple macros or computation to get them.
