[JSC][ARM] Fix stack pointer adjustment in JSToWasm
https://bugs.webkit.org/show_bug.cgi?id=297899
Reviewed by Justin Michaud.
In JSToWasm, we push 8 bytes to the stack before calling
operationJSToWasmEntryWrapperBuildFrame, but when restoring sp,
we would pop 16 bytes, leading to corrupted arguments in the
jitted function.
This PR fixes the issue by poping 8 bytes.
