libmythui: Extend DRM functionality

- there is code for further video related functionality but this commit
just enables mode switching when using MythDisplayDRM.
- mode switching is only available when we have compile time support for
Qt private headers - as these are needed to retrieve various DRM
handles.
- as for the similar raspberry pi specific code, mode switching is
restricted to refresh rate changes only; the Qt eglfs plugin does not
expect anyone else to change the framebuffer size and thus UI
presentation breaks when we change the video mode.
- there may be workarounds available to force Qt to use the largest
possible video mode at startup, and hence the largest possible
framebuffer, and emulate the window size thereafter - but this has not
been tested yet.

libmythtv: Initial support for DRM video rendering

- *HIGHLY EXPERIMENTAL* and *VERY BUGGY*
- to enable runtime support, set the environment variable
MYTHTV_DRM_VIDEO and ensure the Qt QPA platform is explicitly set to
eglfs (either via the -platform command line argument or the
QT_QPA_PLATFORM environment variable)
- I recommend setting 'QT_LOGGING_RULES=qt.qpa.*=true' as well to confirm
that the MythTV internals are consistent with the Qt view of the DRM
world.
- there is a lot going on here - and some of it even works.
- on all platforms tested (amdgpu, pi4 and tanix tx6), video is
displayed when supplied via a DRM decoder (v4l2_m2m, v4l2_request and
VAAPI with DRM).
- that's about as far as the good news gets. On all platforms there is
significant tearing and/or ordering issues with the video, sundry alpha
blending issues with the video and GUI planes and a number of
predictable, unrecoverable Qt rendering failures with AMD.
- Note: I'm fairly sure that no other player supports DRM rendering of
VAAPI decoded frames - and it is only included here for testing
purposes. If it does not work well on Intel based systems it will be
removed.
