[Windows] Always use ANGLE in ARM builds.

[bruvzg]

There's no native OpenGL drivers on Windows for ARM (only software compatibility layer), so ANGLE is a more viable option for compatibility renderer.

Fixes #85961

nice work! as an WOA user, i have already made a minimal project on a Windows on ARM laptop, then test in using opengl3 ANGLE and opengl API 4.1, and then... here are the results.
PS: i use three GPUParticle2D controllers to run. Running in vsync=off, screen_res=(2560,1600,fullscreen), max_fps here sets 0 (the project what i upload sets 60.)

opengl API 4.1: (about 72±6 fps, max_usage=66%, having a opengl->d3d12 translation layer)

opengl3 ANGLE: (about 379±13 fps, sometimes more than 400 fps, max_usage=100%)

72 fps vs. 379 fps, oh my... that's an awesome enhancement!!
PS: i advise to turn off the vsync (might look unsmoothly when enabled) and set max fps as screen refresh rate (e.g. 59, 60, 144, etc.) when choose ANGLE, this test is just for fun.

of course, the more single CPU frequency, the "more" fps (vsync=off), so cpu within low base/turbo frequency is not friendly. then actually watching on the performance of GPU is also worthy. Mine is 3.0 GHz and finally goes about 2.8 GHz because of 100% GPU usage. (but that's still awesome!! thanks to this rendering method, WOA device can really create an amazing game in different genres as well.)

and of course i will only recommend on gpu graphic which needs translation layer, that's because...
eeeh... we can view these two pics (look at fps). here's running on a x86_64 laptop within ATI Radeon HD 7700M.

this is opengl3 ANGLE, the single CPU frequency goes maximum, the GPU-3D usage is less than 50%. con seems more than pro.

and this, is opengl API 4.1. (tears of joy)

so if have a gpu which has enough performance and needn't translation layer (more important), needn't to use ANGLE. :D

Makes sense!

Cherry-picked for 4.2.2.
