Backport of part of #114087 to release/9.0-staging
While doing some testing for work in .NET 10 it was discovered that some of the methods in PackedSimd fail to correctly resolve their interpreter intrinsic and trigger a runtime abort (either a stack overflow or NIY error). This allows the interpreter to correctly resolve the intrinsics for the PackedSimd methods that were failing.
Fixes #114088 and Splat intrinsic uncovered by the tests.
Customer Impact
This is a correctness fix. Anyone attempting to use these Wasm specific methods in non-AOT mode would encounter unrecoverable runtime errors.
Regression
[If yes, specify when the regression was introduced. Provide the PR or commit if known.]
Testing
Test cases included
Risk
Low, the changes avoid runtime aborts and do not touch methods that were working.
