reader/wgsl: Remove old token methods.
This CL removes the old token `Is<Name>()` methods which are no longer
being used in the parser or lexer. (Some of them were used in tests but
the generic `Is(<type>)` is used instead.
New `peek` methods are added which will peek if the given token comes
either next or at the given index.
