Revert "Parially revert fffb138b8175b4838b6a063863756b7c6b2db547"

This reverts commit c487dd2bdb.

Revert the commit that
partially reverted fffb138b81 ...
It turns out that this very much did break IME input, so reverting
this for now. This does make Aegisub use private symbols in wx again,
but the CI builds build wx from the wrap now. Still, this is why
this is on the workarounds branch. If this breaks for too many
people this could either go behind a meson option or be fixed in
some better magical way that I have yet to find.
