*/*: Bump PORTREVISION for known Qt private API abusers

Qt 6.9.2 edition.

These ports are known to directly use or link to a library that uses the
Qt private API and must be rebuilt with every Qt update.

Qt *public* API/ABI compatability is excellent, so most consumers don't
need to necessarily be rebuilt between patch or even minor releases, but
use of the private API breaks this compatibility between even patch
releases and its use is highly discouraged.

This list [1] is based on histortical data. We don't have time to
revisit every port on the list with each Qt update, so if your port has
dropped Qt private headers and was bumped in error, please remove it
yourself if you have write access to the Wiki or alert someone on kde@.

MFH:		2025Q3

(cherry picked from commit ca55e461e4817d34f513f551ef8d788bc46dec0e)

*/*: Bump multimedia/openh264 consumers after dc94e01

net/freerdp{,3} have been already bumped in e447cd0, so not being bumped
again.

The following one-liner was run on the 2025Q3 branch instead of
cherry-picking 17a31bf, as cherry-picking would have resulted conficts.

  $ git grep -l libopenh264 | \
      grep '^.*/.*/Makefile$'| \
      xargs -t -n1 portedit bump-revision -i
