Ensure GLES1 state is cleared on context switch. GLES1 support in multi-context D3D mode is broken prior to this change as state in the GLES1Renderer is not being properly dirtied on context switch. The immediate result is a crash on draw commands due to a null program. Introduce a new dirty bit to specify that the program is dirty and should be re-initialized. Test: GLES1 applications work with the D3D11 backend in multi-context mode.
