Implement proper EGLConfig search+sort+filter in eglChooseConfig.

[juj]

Currently the implementation of the function eglChooseConfig ignores the set of config attributes (the attribList parameter here: 4efdb80#L0R23 ) so it behaves identically to the function eglGetConfig, which returns all the supported configs.

Implement config searching, sorting and filtering according to the EGL v1.4 speficiation in the function eglChooseConfig.

Hello Juj, what would be a good test-case for this, given that only one config is supported - ie, what would we sort/filter with just one candidate ? Do we have to first implement more supported configs before doing this, and if so - what would be those configs that would be of interest ?

[juj]

Yes, we should first add support for enumerating different modes, that doesn't yet exist. Then the sorting/filtering makes sense.

https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.2 shows the different combinations that we are able to support.
