Detect the most suited eGPUBackendType.
Returns true when detection found a supported backend, otherwise returns false. When no supported backend is found GPU_backend_type_selection_set is called with GPU_BACKEND_NONE.

| void GPU_context_begin_frame | ( | GPUContext * | ctx | ) |
Begin and end frame are used to mark the singular boundary representing the lifetime of a whole frame. This also acts as a divisor for ensuring workload submission and flushing, especially for background rendering when there is no call to present. This is required by explicit-API's where there is no implicit workload flushing.

| void GPU_context_main_lock | ( | ) |
Legacy GPU (Intel HD4000 series) do not support sharing GPU objects between GPU contexts. EEVEE/Workbench can create different contexts for image/preview rendering, baking or compiling. When a legacy GPU is detected (GPU_use_main_context_workaround()) any worker threads should use the draw manager opengl context and make sure that they are the only one using it by locking the main context using these two functions.
