- move shader flags from the video drivers to the context drivers
- rework config_load_shader_preset() from configuration.c into retroarch_load_shader_preset() in retroarch.c with proper compatibility check
- implicitly call retroarch_load_shader_preset() in retroarch_get_shader_preset() once per core/content life cycle
- use video_shader_is_supported() instead of video_driver_test_all_flags() where appropriate
- remove GFX_CTX_FLAGS_NONE because it is meaningless
- gl.c: refactor backend fallback into more general gl2_get_fallback_shader_type
- d3d9-12, gl_core, gx2_gfx, gl, vulkan: more consistent shader init and `set_shader` behavior
- configuration.c: remove check_shader_compatibility
- shader_glsl.c, shader_gl_cg.c: use `video_shader_get_type_from_ext`
- shader_gl_cg.c: add shader type check with fallback to stock like in shader_glsl.c
- menu_shader.c: use `enum rarch_shader_type` instead of `unsigned`
- video_shader_parse.c: add `video_shader_to_str` for easier logging
- remove `type` from `struct video_shader`, which was always set to CG and wrongly used in lang_process.cpp's `slang_process()` (has no further consequences because the code is unused)
- video_shader_parse_type()'s fallback only worked for NULL paths and was wrongly used, now returns RARCH_SHADER_NONE like video_shader_get_type_from_ext().
- video_shader_get_type_from_ext() should not be checking video driver flags, this is instead done by video_shader_is_supported()
- video_driver_get_all_flags() did not actually 'get' flags, changed to video_driver_test_all_flags()
workaround for crash due to glcore not always using at least OpenGL 3.2
This allows optionally sorting configure files and is needed to fix the
order of inputs in the autoconfig profiles which should not be sorted
alphabetically.

can load *.slangp and *.slang files. since there is no runtime compiler,
precompiled shaders (*.gsh) need to be present next to each *.slang
source file.
