Add i32 and int32 to Fast API integer validation so optimized calls reject invalid values instead of allowing V8 to truncate them. Signed-off-by: Kamat, Trivikram <16024985+trivikr@users.noreply.github.com> Assisted-by: openai:gpt-5.6-sol

Fixes: #64690
V8’s Fast API converts signed integer arguments to
int32bytruncation. Fast FFI signatures using
i32orint32did not enable theJavaScript integer-validation wrapper, so optimized calls could accept
out-of-range or non-integer values that the generic FFI path rejects.
Add both signed 32-bit type names to the Fast API validation metadata and
native validation-selection check.
