[Clang] Fix coro_await_elidable breaking with parenthesized expressions (#178495 )

The `applySafeElideContext` function used `IgnoreImplicit()` to find the
underlying CallExpr, but this didn't strip `ParenExpr` nodes. When code
like `co_await (fn(leaf()))` was parsed, the operand was wrapped in a
`ParenExpr`, causing safe elide attribution to fail in Clang stage.

This fix chains `IgnoreImplicit()->IgnoreParens()->IgnoreImplicit()` to
handle both orderings of implicit nodes and parentheses in the AST.

Fixes https://github.com/llvm/llvm-project/issues/178256. Except that
`IgnoreParen()` should be a better suggestion than
`IgnoreParenImpCast()`.
