[builtins] Add support for ExternalOneByteStrings to StringEqual.

[builtins] Add support for ExternalOneByteStrings to StringEqual.

The StringEqual builtin can now deal with ExternalOneByteStrings
without going to the runtime. It still needs to go to the runtime
if the external string is short, i.e. if the resource data pointer
is not cached.
