GWN: Add new dynamic type of batches and remove

Theses batches keeps their memory chuck allocated after transfer to be reused and updated very often.

NOTE: This commit break instancing in DRW. (it's fixed in the next commit)

GWN: Add GWN_batch_draw_procedural

This allow to drawn large amounts of primitives without any memory footprint.

GWN: Allow drawing instances without batch_instancing

DRW: Refactor: Make use of the new Gawain long attrib support.

GWN: Extend support for multiple of 4 components in batches.

GWN: Fix style and line of code that does nothing!

GWN: Add support for 4x4 Matrices and instancing attributes.

Only support float matrices specifically for code simplicity.

Cycles: change Index output of Hair and Particle Info to Random, in 0..1 range.

These are used for randomization, so it's convenient if the index is already
hashed and consistent with the Object Info node.

GPU: use alpha blend that works for drawing to transparent buffer.

It's unlikely to ever be intentional to square the source alpha, as happens
with glBlendFunc, so this changes the blending throughout the code.

GPU: don't use multisample for entire window, only for offscreen 3D viewport.

Now that the new 3D viewport draws to a multisample offscreen buffer, there is
no good reason anymore to create an entire multisample window and pay the
performance/memory cost for other regions that don't need it.

GL_MULTISAMPLE now only gets enabled for offscreen buffers, so we don't need
to check for it throughout the UI code anymore.

Differential Revision: https://developer.blender.org/D3062

Fix incorrect RNA path to view_render settings.

Code cleanup: simplify subwindow code.

Particles: Avoid multiple function declarations in multiple places

This makes it really hard to spot errors when function signature changes.

Particles: Cleanup, remove trailign whitespace

Hair child: Use clamp function to clamp curve evaluation

Avoids redundant calls to the curve evaluation.

Math utils: Add clamping functions

CMake: Expose Cycles devices support as CMake option

Handy to disable GPU based devices when it's needed to run Valgrind.

CMake: Fix cimpilation error when CUDA dynload is disabled but toolkit is not installed
