Some cores only work with opengles contexts in wayland.

Description

I decided to try again to use ppsspp in a x11 less environment in RA and found something new and annoying.

It's possible to run ppsspp in a desktop wayland DE without XWayland if you build retroarch with --enable-opengles --enable-wayland (besides disabling x11) and build ppsspp with -DLIBRETRO=ON -DUSING_GLES2=ON -DUSING_EGL=OFF

This is more or less what i expected. Problem; running beetle hw always fallbacks to software even if you built RA with --enable-opengl additionally.

The message is helpful:
[ERROR] Requesting OpenGL context, but RetroArch is compiled against OpenGLES. Cannot use HW context.

This occurs even if you set the core settings to shared context on or off and allow cores to switch video driver on.

Expected behavior

I think this might be happening because the 'gl' option in retroarch is not really 'gl' but a combination of opengl OR opengles OR opengles3, so when the core attempts to switch to opengl it fails. Or maybe once retroarch has a main context type the cores must follow that context but i hope it's not that.

Actual behavior

Fallback to software in beetle (didn't really test other emulators).

Reproduce the issue using the reported RetroArch --enable-opengles --enable-wayland and PPSSPP LIBRETRO, USING_GLES2, and USING_EGL settings, then compare it with --enable-opengl and Beetle HW. No source file or test is identified in the report; done means determining why the OpenGL context request falls back to software, or documenting the supported context limitation.
