Subject: [PATCH] Keep every renderer while raising OpenGL to 3.3

Defining BGFX_CONFIG_RENDERER_OPENGL turned off bgfx's default renderer
list, so the Windows build only had OpenGL and Linux lost Vulkan. Setting
the minimum OpenGL version instead keeps Direct3D 11, Vulkan and the rest.

-The OpenGL renderer needs `BGFX_CONFIG_RENDERER_OPENGL=33`. Without it bgfx targets OpenGL 2.1, compiles the shaders as GLSL 1.20, and strict drivers reject them, which leaves a black screen and then a crash.

 Always give `-j` a number. A bare `-j` starts every compile at once, and on a small machine that runs it out of memory and can freeze the whole desktop. If a low RAM machine with no swap still struggles, use a smaller number than the core count. The same goes for every `make` and `cmake --build` below.
