  [NFC] [ASTMatchers] Share code of `forEachArgumentWithParamType` with UnsafeBufferUsage (#132387)

This changes exposes a low-level helper that is used to implement
`forEachArgumentWithParamType` but can also be used without matchers,
e.g. if performance is a concern.

Commit f5ee10538b68835112323c241ca7db67ca78bf62 introduced a copy of the
implementation of the `forEachArgumentWithParamType` matcher that was
needed for optimizing performance of `-Wunsafe-buffer-usage`.

This change shares the code between the two so that we do not repeat
ourselves and any bugfixes or changes will be picked up by both
implementations in the future.
