Fix compile error when building without OpenSubDiv

OpenSubDiv: add support for an OpenGL evaluator
This evaluator is used in order to evaluate subdivision at render time, allowing for
faster renders of meshes with a subdivision surface modifier placed at the last
position in the modifier list.
When evaluating the subsurf modifier, we detect whether we can delegate evaluation
to the draw code. If so, the subdivision is first evaluated on the GPU using our own
custom evaluator (only the coarse data needs to be initially sent to the GPU), then,
buffers for the final `MeshBufferCache` are filled on the GPU using a set of
compute shaders. However, some buffers are still filled on the CPU side, if doing so
on the GPU is impractical (e.g. the line adjacency buffer used for x-ray, whose
logic is hardly GPU compatible).
This is done at the mesh buffer extraction level so that the result can be readily used
in the various OpenGL engines, without having to write custom geometry or tesselation
We use our own subdivision evaluation shaders, instead of OpenSubDiv's vanilla one, in
order to control the data layout, and interpolation. For example, we store vertex colors
as compressed 16-bit integers, while OpenSubDiv's default evaluator only work for float
In order to still access the modified geometry on the CPU side, for use in modifiers
or transform operators, a dedicated wrapper type is added `MESH_WRAPPER_TYPE_SUBD`.
Subdivision will be lazily evaluated via `BKE_object_get_evaluated_mesh` which will
create such a wrapper if possible. If the final subdivision surface is not needed on
the CPU side, `BKE_object_get_evaluated_mesh_no_subsurf` should be used.
Enabling or disabling GPU subdivision can be done through the user preferences (under
Viewport -> Subdivision).
See patch description for benchmarks.

: Mesh sequence cache, crash when clicking a panel
The crash happens when opening a panel (added in rB43f5e761a66e87fed664a199cda867639f8daf3e
when no CacheFile is set in the modifier.
To fix this, check that the CacheFile pointer is not null before attempting to draw anything.

Cache File: use panels to organize UI
This adds interface panels to organize the Cache File UI parameters for
modifiers and constraints into related components: velocity, time, and
Properties relating to the three aforementioned components are separated
from `uiTemplateCacheFile` into their own functions (e.g.
`uiTemplateCacheFileVelocity` for the velocity one), which are in turn
called from the specific panel creation routines of the modifiers and
constraints (for constraints, the functions are exposed to the RNA).
`uiTemplateCacheFile` now only shows the properties for the file path,
and in the case of constraints, the scale property.
The properties that are only defined per modifier (like the velocity
scale), are shown in the proper modifier layout panel if applicable.

Fix missing type declaration compile errorrBbd3bd776c893
broke compilation here due to missing type declaration
for basic types as the source file is not including this header. In any
case, it is the responsibility of header files to include headers for
types used by value in function parameters or struct definitions.

GPU: add memory barriers for vertex and index buffers
This adds memory barriers to use with `GPU_memory_barrier` to ensure that
writes to a vertex or index buffer issued before the barrier are
completed after it, so they can be safely read later by another shader.
`GPU_BARRIER_VERTEX_ATTRIB_ARRAY` should be used for vertex buffers (`GPUVertBuf`),
and `GPU_BARRIER_ELEMENT_ARRAY` should be used for index buffers (`GPUIndexBuf`).
