d3d11: Add support for HLSL precompile and shader caching
...
Compile HLSL at build time in case of MSVC, and use it if device
supports shader model 5. Also cache/reuse pixel shader and vertex
shader objects.

d3d11videosink: Fixing unexpected overlay composition meta drops
...
A buffer can hold multiple GstVideoOverlayCompositionMeta objects.
Should scan all metas on a buffer and render all overlay rectangles
if any.

d3d11overlaycompositor: fix texture width and height
...
The dimension of the overlay texture directly corresponds to the size of the overlay **buffer** which is given by its video meta.
The dimension at which the overlay should be displayed directly correspond to the overlay `render_width`and `render_height`.
This match the behavior of glimagesink

d3d11: Move HLSL compiler to gst-libs
...
We should move this functionality to gst-libs so that GstD3D11Converter
can be moved to gst-libs.
Another advantage is that applications can call our
HLSL compiler wrapper method without any worry about OS version
dependent system installed HLSL library.
Note that there are multiple HLSL compiler library versions
on Windows and system installed one would be OS version dependent.
