[PATCH v2 0/2] MR7465: winegstreamer: Validate the value of cbSize in aac decoder.

[Brendan McGrath (＠redmcg)]

This MR fixes a mf:transform test that started failing as a result of MR !7417.

It also adds new tests to mf:transform to test different values of `MF_MT_USER_DATA` against the aac decoder.

It adds validation of `cbSize` to the aac decoder, which, in addition to fixing the previous test, allows some of these new tests to pass. But it does not validate the content of the user data (as the new tests seem to indicate Windows does).
