Summary [meta] Add an "IDL attribute checker" to detect typo of IDL attributes

We have fixed 10~ bugs caused by typos of IDL attributes. Now we need an "IDL attribute checker", which checks if IDL attributes not implemented in code generates are not used in IDL files. - The "IDL attribute checker" uses IDLAttributes.txt, which lists all IDL attributes implemented in code generators. If we want to add a new IDL attribute, we need to add it to IDLAttributes.txt manually. - The "IDL attribute checker" checks if all IDL attributes used in IDL files are listed in IDLAttributes.txt. - If the "IDL attribute checker" fails, the build fails with a verbose error message. Considering the following build flow, I guess that resolve-supplemental.pl would be the right place to add the "IDL attribute checker". supplemental_dependency.tmp: $(ALL_IDLS) perl resolve_supplemental.pl ... JS%.cpp : %.idl supplemental_dependency.tmp perl generate-bindings.pl ... To avoid build regression, I am planning to land the patch in the following steps: - Enable the "IDL attribute checker" in Chromium. - Enable the "IDL attribute checker" in all other build systems. - Rename resolve-supplemental.pl to preprocess-idls.pl.
