Unfortunately, I do not think we can. That was the way I originally tried to
implement it. It worked on no-namespace-check, but not in this one. This is
because as an AST_POLYMORPHIC_MATCHER_P, we are trying to match an usage of a
Decl, not the Decl itself and since we are matching a TypeLoc in
no-internal-deps-check, not really the usage, it doesn't work.
As a result, I modified my original implementation, which you will see in
no-namespace-check and turned it into IsInAbseilFile(SourceManager&,
SourceLocation), which is just takes a source location and returns whether the
location we matched is in an Abseil file
