Work around GCC 14+ false -Wuninitialized in Variant
https://bugs.webkit.org/show_bug.cgi?id=317745
Reviewed by Nikolas Zimmermann.
GCC 14 through 16 report mpark variant's index_ as used uninitialized when
valueless_by_exception()/index() inline into
HashMap<GenericHashKey<...>, ...>::remove(), even though index_ is set by
every base constructor. This breaks --fatal-warnings builds (e.g. Ubuntu
26.04 / GCC 15). Suppress -Wuninitialized around the two accessors on GCC;
clang and GCC <= 13 are unaffected.
