Texture render support (#934)

Browse Source 
Technically unimpressive, but I had to go through quite a good amount of
changes. Here is the full changelog to make everything work:

* Ensure `ResetPlatform` is always called to avoid memory leaks
* Add `g_RawVram` to emulate the PS1 VRAM
* ~~The engine will load the optional file `disks/vram.bin`, a RAM dump
from an emulator~~
* SDL2 will create 256x256 textures on-the-fly whenever a specific tpage
is requested via `GetVramTexture`
* The function `GetVramTexture` caches the last called tpage to avoid
tanking the performance
* `GetVramTexture` for only renders 4bpp and 8bpp textures with their
specified palette
* Remove `SDL2_image` as the font is now loaded straight from the VRAM
* Calling `VSync` will call the set callback, which the game uses for
DMA operations
* `MyLoadImage` is not yet implemented, but it is a placeholder to then
interact with `g_RawVram`
* The menu font now uses the texture found in the VRAM
* Plugged a custom version of `LoadFileSim`
* The file `sim_pc.c` is similar to the original game's code but it is
used here to load files from custom paths
* Using F5, F6 or F7 can dump the VRAM content on-screen, respectively
in 16bpp, 8bpp and 4bpp

There are new graphical glitches on the font. In some occasions it
appears black. It seems to be related to a flag in `P_TAG.code`. I plan
to dig into it when I can render entities on screen to avoid potential
mistakes. The same problem is present for the first half of Alucard's
portrait. It seems to be related when a texture is transparent? 🤷

I am not sure why the font is completely corrupted when entering in the
Equip menu. It is hard to understand if I introduced any regression.
Maybe the glitch was always there but it was hidden since I was always
forcing the font texture to be rendered.

EDIT: Implemented `LoadImage`, `SaveImage` and `ClearImage`

FindSDL2_image
--------------
Locate SDL2_image library
This module defines the following 'IMPORTED' target:
::
SDL2::Image
The SDL2_image library, if found.
Have SDL2::Core as a link dependency.
This module will set the following variables in your project:
::
SDL2_IMAGE_LIBRARIES, the name of the library to link against
SDL2_IMAGE_INCLUDE_DIRS, where to find the headers
SDL2_IMAGE_FOUND, if false, do not try to link against
SDL2_IMAGE_VERSION_STRING - human-readable string containing the
version of SDL2_image
This module responds to the following cache variables:
::
SDL2_IMAGE_PATH
Set a custom SDL2_image Library path (default: empty)
SDL2_IMAGE_NO_DEFAULT_PATH
Disable search SDL2_image Library in default path.
If SDL2_IMAGE_PATH (default: ON)
Else (default: OFF)
SDL2_IMAGE_INCLUDE_DIR
SDL2_image headers path.
SDL2_IMAGE_LIBRARY
SDL2_image Library (.dll, .so, .a, etc) path.
Additional Note: If you see an empty SDL2_IMAGE_LIBRARY in your project
configuration, it means CMake did not find your SDL2_image library
(SDL2_image.dll, libsdl2_image.so, etc). Set SDL2_IMAGE_LIBRARY to point
to your SDL2_image library, and configure again. This value is used to
generate the final SDL2_IMAGE_LIBRARIES variable and the SDL2::Image target,
but when this value is unset, SDL2_IMAGE_LIBRARIES and SDL2::Image does not
get created.
$SDL2IMAGEDIR is an environment variable that would correspond to the
./configure --prefix=$SDL2IMAGEDIR used in building SDL2_image.
$SDL2DIR is an environment variable that would correspond to the
./configure --prefix=$SDL2DIR used in building SDL2.
Created by Amine Ben Hassouna:
Adapt FindSDL_image.cmake to SDL2_image (FindSDL2_image.cmake).
Add cache variables for more flexibility:
SDL2_IMAGE_PATH, SDL2_IMAGE_NO_DEFAULT_PATH (for details, see doc above).
Add SDL2 as a required dependency.
Modernize the FindSDL2_image.cmake module by creating a specific target:
SDL2::Image (for details, see doc above).
Original FindSDL_image.cmake module:
Created by Eric Wing. This was influenced by the FindSDL.cmake
module, but with modifications to recognize OS X frameworks and
additional Unix paths (FreeBSD, etc).
