  [flang] Improve OpenACC SELF clause parser (#135883)

The current parser can fail on "self(x * 2)" by recognizing just "x" as
a one-element list of object names and then failing at a higher level
because it never reached the right parenthesis. Add lookahead checks and
error recovery.

Fixes https://github.com/llvm/llvm-project/issues/135810.
