install_deps: fix several issues.

Lots of fixes and cleanups, mainly addressing:
* OpenEXR building was fully broken.
* Missing dependencies of Alembic to Boost and openEXR.
* OSL had changed its CMake parameters for custom OpenEXR install path.
* Dependencies between libs were not properly handles when switching a
lib from own build to system package.

EEVEE: First Buffer Drawn Incorrectly

SSS buffers are lazy initialized when needed. When shaders recompile the
SSS buffers could be incorrectly drawn. During the render passes project
we tried to fix this, but that resulted in incorrect result of the first
sample after a shader was compiled.

We revert this change knowing that we know the issue, but haven't found
a proper solution for it.

Cycles: Add option to change which sample to start viewport denoising at

This patch adds a new user-configurable option to change at which sample viewport
denoising should kick in. Setting it to zero retains previous behavior (start immediately), while
other values will defer denoising until the particular sample has been reached. Default is now
at one, to avoid the weirdness that is AI denoising at small resolutions.

UI: Add theme option for time markers line

This patch adds the ability to set colors and alpha of dashed line of
Time Markers. That way themes can avoid contrast issues and communicate
selection better. See screenshots in D6877.

GPU: Add Image property to allow high bitdepth support on a per image basis

This adds the `Half Float Precision` option in the image property panel.
This option is only available on float textures and is enabled by default.

Adding a flag inside the imbuf (IB_halffloat) on load is done for EXR and PSD formats that can store half floating point (16bits/channels).
The option is then not displayed in this case and forced.

Ocean modifier: fix changes to resolution complete changing the shape

This takes the idea from the aaOcean library to link the RNG seed to the
surface point, so that changing resolution only adds/remove surface detail.
