3.2: Software Skinning being used despite hardware capability

[lyuma]

Godot version:
0a2a93b

OS/device including version:
Windows 10 [10.0.18362.1082]
NVIDIA GeForce RTX 2080 Ti
Driver 452.06

Issue description:
With the new PR that landed, Godot appears to be using software skinning (as evidenced by a new rendering bug) both in a case where I created a new project and in a case where I open an older existing project.

The expected behavior is to whitelist the specific low-end hardware which needs to use software skinning, so as to not degrade performance on high-end systems.

Steps to reproduce:

1. Make a new project
2. Import a GLB with blend shapes.
3. Switching tabs to a model with blend shapes is perceptibly slower (I think about 0.2 seconds, compared with instantaneous) with a new release build compared to 3.2.3.stable. See here for the test project with this model regression in 3.2 branch: nondeterministic Blend shape rendering glitch #42767

Regression fixed by #42846. (#37854 is still valid.)
