Compiling this big file for every Eevee material is bad for performance, and
now that we are adding more nodes it gets worse. This patch adds a simple
mechanism to split up that file, and use only the parts used by shader nodes.
When a function is used by GPU_link, we detect which GLSL file it came from
and use it in GLSL code generation automatically. Dependencies between GLSL
files are manually specified, and function names must be unique across all
GLSL files.
Most of the actual splitting up will be done in later commits.

Previously there was already "draw_shape" property,
but it was doing nothing. This commit renames the
property to "display_shape". Furthermore, different
shapes like SQUARE and DIAMOND are supported now.
Currently, the shapes are drawn using the shader that also
draws keyframes. In the future we might want to separate
this.
The new shapes are not used anywhere yet, but they can
be used by addon developers and will probably be useful
when we want to support different kinds node systems later.
For example, different shapes can be used to distinguish
between data and control flow.

The White Noise node hashes the input and returns a random number in the

Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap,
Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators
to the Vector Math node. The Value output has been removed from operators
whose output is a vector, and the other way around. All of those removals
has been handled properly in versioning code.
The patch doesn't include tests for the new operators. Tests will be added
in a later patch.

This is done because they don't have the same update frequency. UV can be
persistent even on geometry update (ex: skinned object) but tangents
can change if the normals change.
Also the name buffer per vbo was too small to contain all names.
For clarity sake, the batch cache now uses exclusively per Loop attributes.
While this is a bit of a waste of VRAM (for the few case where per vert
attribs are enough) it reduces the complexity and amount of overall VBO
to update in general situations.
This patch also makes the VertexBuffers filling multithreaded. This make
the update of dense meshes a bit faster. The main bottleneck is the
IndexBuffers update which cannot be multithreaded efficiently (have to
increment a counter and/or do a final sorting pass).
We introduce the concept of "extract" functions/step.
All extract functions are executed in one thread each and if possible,
using multiple thread for looping over all elements.

Previously, we had one global `GPU_matrix` stack, so the API was not
thread safe. This patch makes the stack be per `GPUContext`, effectively
making it local per thread (`GPUContext` is located in thread local
storage).

The problem is that the `glDrawArraysInstancedBaseInstance` is ignoring the last parameter.
The solution is to indicate that `GLEW_ARB_base_instance` is not supported in these cases.

When using opengl attributes such as gl_VertexID in a shader its

attribute array. This fails big time when called from python. For
