Turn off debug file writing in boolean etc unit tests.

Also, for Windows, do something other than /tmp when file writing
is turned on. This file writing is only intended for debugging.

GPU: Vulkan: Add creator arg to enable vulkan drawing

The creator arg is meant to support more than vulkan or opengl.

This currently fails because there is no GPU backend separation.

Note that we use G.debug with a debug flag to know what context type to
create. This will need to be cleaned later.

GPencil: Basic structure of layers

The problem was the Region was NULL, but now using a function the region is right.

Cleanup: silence clang-tidy warnings; comments.

Use static_cast wherever applicable.

Pass struct by reference.

Remove unnecessary const qualifiers for primitive types.

Make some member functions static instead.

Remove intermediate non-owning pointers to new class instances.

Remove else in else-after-return.

Initialise variables at definition.

Fluid: Added an option for color mapping pressure grid

GHOST: Vulkan: Support window resizing

GPencil: WIP delete curve points

GHOST: Vulkan: Style Cleanup

GHOST: Vulkan: Better debug messages

Merge branch 'blender-v2.90-release'

Merge remote-tracking branch 'DarkdefenderRepo/npr_tess_2_90' into lanpr-under-gp

GHOST: Vulkan: Remove swap interval functions

Keep vertex deform group names and def_nr in sync

I realised later on that Map is unordered, so the order of insertion,
on which def_nr depends, is not retained. So a Vector of strings
has been used & the index of the string-of-interest is the def_nr.

Unfortunately, it will be slow on large number of vertex groups.

Cleanup make function private

Cleanup: Rename 'isect_ray_seg_v3' to 'isect_ray_line_v3'

The name was misleading as it returns true whenever it intersects the
line represented by the points.

Fix memory leak

GHOST: Vulkan: Add Test command buffers and sync primitives

LineArt: Use separate function for getting closest end point in chain.
