OpenGL: remove use of GLEW MX

MX (Multiple conteXt) support was dropped from the GLEW 2.0 library to make core profile support cleaner.

Our WITH_GLEW_MX build option was OFF by default already; this commit removes the inactive code paths.

I'm working on a plan for multiple GPUs, contexts, resource sharing, etc. This commit gives us a cleaner starting point for that upcoming work.

Tested on Mac, will test on Linux & Windows immediately after pushing.

OpenGL/GHOST: don't request accum buffer on Mac

This was blocking core context setup on Mac, since accumulation buffers are obsolete. With this (and appropriate CMake options) I now get

renderer: 'Intel HD Graphics 4000 OpenGL Engine'
vendor: 'Intel Inc.'
version: '4.1 INTEL-10.24.45'

in system-info.txt intead of

version: '2.1 INTEL-10.24.45'

fix unitizialized use warning

The code would only use 'type' uninitialized in error conditions, but it's still better to avoid that.

Eevee/OpenGL: fix shader for core profile

[cmake] Fix Alembic build errors with msvc

Eevee: Cascaded Shadow Maps, follow up.

- Compute coarse bounding box of split frustum. Can be improved
- Make use of 4 cascade.
- View dependant glitches are fixed.
- Optimized shader code.

Fix crash when duplicating objects by tagging depsgraph

This may change once depsgraph becomes aware of workspaces.
For now this is the best we can do.

Alembic unit tests: Removed trailing spaces

Alembic unit tests: don't depend on ALEMBIC_ROOT_DIR being defined by user

By mistake, the code relied on ALEMBIC_ROOT_DIR being defined by the user
running the tests. Now CMake macros are used to correctly find the Alembic
root directory.

Re-enabling Alembic test

(disabled because of bug fixed on 19548040d91dedc2a63444f3277e4365837931e1)

Matrix.decompose(): changed terminology, "location" ? "translation"

Matrix.decompose() should either return "location, orientation, size" or
"translation, rotation, scale". Since there are constructors for the former,
I've replaced "location" in the documentation with "translation".

The code is still the same, I just changed the documentation.

Fix T51261: New objects aren't selected

The original code was failing because the base to object flushing was
only happening as part of the depsgraph. However we can use the
evaluated values to set the initial values of the base.

In this particular case, we couldn't set the new object visible because
its selectability flag was not set yet.

Fix objects visibility evaluation bug

This was introduced on 4b77fb30759d1b62224033fc92c55eef7f3e414a no idea how I left this in, shame on me

Tag depsgraph update when hide and hide_select are changed

We were not updating depsgraph when collection just "became" selectable,
but although this doesn't change object selection, it change its
selectability.

Cycles: Solve speed regression of classroom scene after principled commit

This way we can skip it from compiling into OpenCL kernels by making
this shader compile-time feature.

Cycles: Make it a generic base class for all types of closure nodes

The idea is to have osme geenric BSDF node which is subclassed by
"regular" BSDF nodes and uber shaders.

This way we can access special type and closure type for making
decisions somewhere else.

CMake: Add option to build against system-wide Glog

Similar to previous commit for Gflags.
