[JSC] many-substrings-of-rope-shouldnt-use-excessive-memory-2.js.default
fails on WPE
https://bugs.webkit.org/show_bug.cgi?id=306952
Unreviewed test gardening.
This test was skipped for WPE/x86_64 on 306795@main but it is also failing
for
WPE/ARM64, so make the skip more generic.

[JSC] wasm/js-api/Instance.imports.exports.unicode.js: reuse the import and
export descriptor arrays instead of rebuilding them for every check
https://bugs.webkit.org/show_bug.cgi?id=320756
Reviewed by Yusuke Suzuki.
Cache the import and export descriptor arrays before checking their
contents.
Calling WebAssembly.Module.imports() for every imported name rebuilt the
import descriptor around ~961 times and the export one around 31 times,
causing excessive allocation and garbage collection without adding test
coverage.
This was causing this test to be very slow on Release+Asserts for WPE ARM64,
usually timing out.
After this fix the total time to run it went from several minutes to less
than 2 seconds
