DRW: Remove the use of GPUTexture buffers for edit wire rendering

See previous commit for detail as why.

DRW: Rework wireframe overlay implementation

The shader is way simpler and run way faster on lower end hardware
(2x faster on intel HD5000) but did not notice any improvement on AMD Vega.

This also adds a few changes to the way the wireframes are drawn:
- the slider is more linearly progressive.
- optimize display shows all wires and progressively decrease "inner" wires
intensity. This is subject to change in the future.
- text/surface/metaballs support is pretty rough. More work needs to be done.

This remove the optimization introduced in f1975a46390a5bf85bb7012375f9bc1e761fc516.
This also removes the GPU side "sharpness" calculation which means that
animated meshes with wireframe display will update slower.
The CPU sharpness calculation has still room for optimization. Also
it is not excluded that GPU calculation can be added back as a
separate preprocessing pass (saving the computation result [compute or
feedback]).

The goal here was to have more speed for static objects and remove
the dependency of having buffer textures with triangle count. This is
preparation work for multithreading the whole DRW manager.

GPU: Remove EXT and add assert

Some drivers accept shaders with only vertex stage, but some just silently
fails.

GPU: Add GPU_vertformat_triple_load to load next vertices attrib

Right now does not add padding at the end of the buffer.

This seems not necessary but may cause problem on some platform. If needed
we will add this padding (only 2 more vertices).

DRW: Add Provoking vertex state.

Fix T58904: Side tabs disappear when creating new View Layer

Using listener here, although I suspect we should be using message
subscriber only. That said, this mimics the behaviour of the buttons
main region.

As for the original bug report what was happening was that when
switching between viewlayers (or when creating one) we may not get the
same active object. So the context breadcrumbs are different.

And the bug itself was that we were missing a redraw on view layer
change.
