Handle refresh rate as float in general, and add also extra
attributes (interlaced, doublescan) for video modes.
Make it possible to select exact mode (interlaced / doublescan modes
will not be selected), and allow close matches such as 49.5 Hz
for PAL 50 Hz.
Change GL2, GL3 and Vulkan drivers to behave as fullscreen if context driver
(such as KMS/DRM or KHR) does not support windowed mode at all.
Take it into account also for refresh rate switch.
* [WINRT] Enable logging on __WINRT__ and bypass verbosidy in debug
* [UWP] wrong configuration prevents GLES to compile, common functions defines GL symbols
* [UWP] configure project to allow OPENGL on default configuration and copy MESA DLLs into UWP release
* [UWP] add MESA headers
* [UWP] add MESA EGL.lib needed for GLES context. However HAVE_OPENGL is better as GL cores use desktop version, so this is left for reference and to make the solution build with HAVE_OPENGLES
* [UWP] UWP is missing some GDI function definitions, implemented into MESA Gallium
* [UWP] Configure Release project too
* [UWP] Add mesa alpha-2 release dlls
* [UWP] allow griffin and vide_driver to have an OPENGL context
* [UWP] allow wgl context to work with mesa under WINRT
* [UWP] BUG: have to modify height/width getters and align them to MESA because the screen resolution is not right in gl context. Pending further investigation
* [UWP] fix ANGLE build
* [UWP] remove duplicate import code.
* (UWP) Cleanup filters file
* MESA screen destroy fix and Yabasanshiro hack. Align to alpha-2-hack tag

Adds support for sub-frame shaders to vulkan/glcore/dx10-11-12.
Builds on the concept already present for frame duplication in use for BFI, to present multiple 'sub' frames per real frame to the shaders, so they can run at a higher framerate than the content framerate. Must be enabled via subframe shaders setting under synchronization settings to be active.
Will allow BFI to be implemented inside of the shaders, among any other use for the higher framerate shader authors can devise.
CurrentSubFrame and TotalSubFrames have been available inside the shaders to track what they want to do on an given subframe. TotalSubFrames will always be 1 when the setting is disabled (and when in menu/ff/pause). Framecount will not increment on sub-frames, as it does not for injected bfi frames now. Should not interfere with any existing shaders that do not check for subframes.

BFI Updates
Significant BFI updates.
- Adds BFI to dx10/11/12 in general.
- Updates existing BFI menu option descriptions to be somewhat more clear in how to use correctly.
- Adds Variable Strobe length via new 'Dark Frames' bfi sub-choice. Only valid at 180hz and above, as it must work with whole frames.
- Algorithm to auto select 'decent' Dark Frames choice, for any given selected BFI refresh rate. Will also avoid defaults that can cause Image Retention at any Hz higher than 120. (Impossible to avoid at 120 if you have an affected screen... get an OLED :D ) .
- Some sanity checking on selecting BFI or the other synchronizations options like Swap Interval > 1, that don't play well with BFI.
Adds overlay_cache_ptr to keep a disabled overlay in memory when it's expected to be shown again.
Most input_overlay_deinit calls are replaced with input_overlay_unload, which caches the overlay unless initing/deiniting core or disabling overlays.
Loading a cached overlay is done as a swap, intended for osk_toggle.
Related updates:
- Fewer parameters for the overlay loading task. Use current settings when enabling an overlay
- Add input_overlay_check_mouse_cursor() to preserve show/hide mouse behavior
- Don't apply input_overlay_show_mouse_cursor in windowed mode (controlled by mouse grab only)
- Remove some dead code
