  [clang][CUDA/HIP] Fix parsing of `operator<<<...>` (#218384)

In CUDA mode Lexer merges `<<<` into a single token and Parser fails to
recognize that it is actually a template specialization of `operator<<`
and not a CUDA kernel call expression. Split `<<<` following operator
token to `<<` and `<`.
