Beetle PSX implementation of "psx.correct_aspect" introduced in Mednafen
1.24.0-UNSTABLE (no relevant code backported from upstream).
Additionally fixes aspect ratio scaling issues when cropping overscan or
adjusting visible scanlines. "Force 4:3" is left as a legacy option for
users preferring the old inaccurate behavior.
Core now properly falls back to software renderer when requested
hardware context is not Vulkan/OpenGL instead of defaulting to Vulkan
for every context other than OpenGL. Core now also checks each hardware
renderer instead of only Vulkan for frontends that do not support
RETRO_ENVIRONMENT_GET_PREFERRED_HW_RENDER.
Makes cstring comparison style consistent within each file, based on the
most common style for each individual file. RSX uses !strcmp while
libretro.cpp uses strcmp == 0. Also minor whitespace fixes.

* Shared memcards and memcard0 method core options are now only checked in retro_load_game and require a restart
* In retro_load_game, rsx_intf_open is called first before check_variables and alloc_surface
* check_variables no longer receives any params
* Ensure none of the renderers call SET_SYSTEM_AV_INFO before we're in retro_run
* Ensure the first iteration of retro_run checks core options even if they weren't updated yet
* Store the upscale shift when calling GPU_Init() and prevent calling delete on a null pointer in GPU_Rescale()
* VK renderer now outputs psx vram fb within proper display area
* Implement and reenable horizontal overscan cropping option
* Update rsx and Vulkan rsx playback for new VK renderer code
