QRhiD3D12: make static const members constexpr to avoid linker error

The static const members need to be constexpr when compiling with
llvm-mingw - otherwise there will be an undefined reference, at least
when doing a unity build.

qpa/wayland: Only enable text-input-v3 surfaces when needed

Since a2bc24c05189f9d39c034560f163ad1490c37996,
enabling and disabling surfaces in text-input-v3 has been tied to
receiving enter and leave events for those surfaces. This is incorrect
as a surface may be entered but should not be enabled, for example if
the current focused object does not support text input.

[ChangeLog][QtCore][qpa/wayland] Make it so that surfaces under
text-input-v3 are only enabled if they are entered and want to receive
text input.

Fixes: QTBUG-146211
