UV: support select linked with sync-select in vert/edge modes

Fix T46568: UV select-linked failure to de-select

Shift-L was de-selecting all instead of the linked UV's.

Fluid: Another adjustment for Python pointers

Yet another update to ensure that pointer variables are always up to date, i.e. those referencing the memory allocated by Mantaflow. Outdated pointers usually show up through flickering in viewport.

Fix T78884: GPencil weight paint crash when painting over modifier generated points

The weight must be added only to the real points, not to the autogenerated points by modifiers. This affects, not only to subdivide, but to any modifier that generate points.

Fluid: Fix for Python pointer update (flickering in smoke/fire issue)

In f2b04302cdec the pointer update was refactored. It was sufficient to update pointers just in replay mode at the end of a step since the 'ensure()' functions from manta_fluid_API.cpp had their own pointer update call. These were removed in 51f4bee5a5d7, however, and so in order to still have some sort of update, the given update call needs to be available to all cache types.

Deps builder: Add support for building GMP

Required for the new boolean code, disabled by default
until all platforms have landed the libs and the boolean
code actually lands in master.

Fix T79111: Cycles: Image Sequence not rendering

Caused by c7aa0f9d743ee9cafe91b4a51d9f1ecc5e437d71.

Since above commit, BKE_image_user_frame_calc requires an image (not
just the iuser) to get the framenumber.

Cycles used to call this with NULL image (in `image_user_file_path` and
`image_user_frame_number`), now pass the image as well.

Fluid: Cleanup and improved readability

A collection of multiple changes that had been living in my stash:

- Use nullptr instead of NULL in C++ files
- Removed unused/deprecated functions from headers
- Cleared animatable flag in cache UI
- Comment cleanups

Fluid: Refactored Python fluid initialization functions

Initialization functions now have a return type which will be asserted during fluid object creation.

Fluid: Refactored Python pointer update function

Use static_cast() where possible and refresh pointers for every frame when in replay mode. The latter is particularly important as this seems to have caused the issue where smoke in the viewport was flickering when loading data from pointers after loading them from disk for the frame before (e.g. when resuming a bake job).

Fix T78600: Crash when transforming doubles with mirroring on

`EDBM_verts_mirror_cache_begin_ex` could do a better work avoiding these
duplicates, but this is a separate problem.

Fluid: Fix missing WITH_FLUID in draw code

The new draw code from 486c7b87fb06 was just missing a WITH_FLUID flag.

Fix blender_test runner build on the buildbot on Linux and macOS

Add our own copy of the gtest discovery scripts from CMake a few reasons:
* Use the very latest version which supports PRE_TEST for Windows
* Fix usage of [] symbols in file paths that fail with the zsh shell
* Disable asan leak checker when discovering tests

This means Windows also no longer requires the very latest CMake 3.18.
