  [OpenACC] Implement ignoring of extension clauses

OpenACC 3.4 will permit extension clauses, which are clauses that start
with '__', and contain an optional balanced-paren-token-sequence inside
of parens.

This patch ensures we consume these, and emit a warning instead of an
error for unsupported clauses.
