[PATCH] Revert "meson: Deprecate bitwise operations between different enumeration type"

[Laurent Pinchart]

Enabling -Wdeprecated-enum-enum-conversion by default turned out to be a
too hasty decision. It causes compilation failures with Qt headers prior
to Qt v5.15.8. As the previous LTS versions of Debian and Ubuntu ship
older Qt versions, those errors cause real inconvenience to users.

This reverts commit bf4695266bfca8cc21bcf10a3281e874ebce0d27.

The original goal of avoiding C++20 compilation regressions is still
handled through a test in CI.
