Make runtime shader compilation optional (#251)
* Move shader compilation to libcute-shader * Fix user shader compilation * Remove unnecessary include * Make cf_make_shader_from_bytecode more friendly to code generator * Add cute-shaderc * Implement draw shader compilation * Fix syntax error in generated header * Pre-compile builtin shaders * Pre-compile imgui shaders * Update hello_triangle sample * Update shallow_water sample * Update recolor sample * Update spaceshooter example * Update waves sample * Update metaballs sample * Make CI build both variants of CF_GLSLANG * Skip uploading artifact for variant without runtime shader compilation * Ensure that src/data/builtin_shaders_bytecode.h is rebuilt when needed * Simplify hello_triangle sample * Enable PIC in libcute-shader when building CF as a dynamic library * Stack allocate the list of builtin includes * Add VFS support in cute-shader * Make the runtime compiler lookup cf_shader_directory for include * Revert samples which uses inline shader * Add preprocessed shader source as comment in generated header * Style fix * Remove unnecessary dependencies * Add reflection info to shader compiler * Make CF use reflection info from cute-shader * Make CF and cute-shader share the CF_ShaderBytecode definition * Add extern "C" * Fetching and building of glslang optional * Make workflow use the new options * Add doc to CF_ShaderInputInfo * Clean up * Add -obytecode= to cute-shaderc to write raw SPIRV blob * Create documentation for changes * Typo and wornding in doc * Update coding style to follow CF convention * Add const to NULL declarations This allows the header to be compiled as C too.

|

| Creates a custom draw shader from bytecode. | ||
|
|
||
| ```cpp | ||
| CF_Shader cf_make_draw_shader_from_bytecode(CF_DrawShaderBytecode bytecode); | ||
| ``` | ||
| ## Remarks | ||
| Your shader must be written in GLSL 450, and must follow some specific rules to be compatible with the draw API. For more in-depth explanations, | ||
| see CF's docs on [Draw Shaders](https://randygaul.github.io/cute_framework/#/topics/drawing?id=shaders). | ||

| Free a bytecode blob previously returned from [cf_compile_shader_to_bytecode](/graphics/cf_compile_shader_to_bytecode.md). | ||
|
|
||
| ```cpp | ||
| void cf_free_shader_bytecode(CF_ShaderBytecode bytecode); | ||
| ``` | ||
| Parameters | Description | ||
| --- | --- | ||
| bytecode | The bytecode blob to free. | ||
| ## Remarks | ||
| This function must only be called on the bytecode blob returned from [cf_compile_shader_to_bytecode](/graphics/cf_compile_shader_to_bytecode.md). | ||
| It cannot be called on the bytecode blob generated as a header from the `cute-shaderc` compiler. | ||
