Use a stamp file for JS bindings generation to avoid O(n*m) make dependency
overhead
https://bugs.webkit.org/show_bug.cgi?id=312838
Reviewed by Elliott Williams.
The generate-bindings-all.pl make rule used ~3,646 pattern targets
(one per JS*.h and JS*.cpp), each depending on all ~1,823 IDL files.
This caused make to perform O(n*m) prerequisite stat calls (~15 seconds
of overhead) before even running the Perl script. Replace with a single
stamp file target so make checks dependencies only once.
* Source/WebCore/DerivedSources-output.xcfilelist: Add .js-bindings-stamp
to output file list and fix alphabetical ordering of JSWebXRSession entries.
* Source/WebCore/DerivedSources.make: Replace ~3,646 pattern targets for
JS bindings with a single .js-bindings-stamp target, avoiding O(n*m)
make dependency checking overhead.
