Iago Toral Quiroga 05cf7b0594 v3dv/blit: fix integer blits from larger to lower bit size
In this case the hardware seems to copy the bits that actually fit
in the destination instead of clamping to the maximum value allowed
by the bit size of the destination components like Vulkan expects.

Fix this by adding code to clamp the color results to the bit size
of the destination components.

It should be noted that this is a general issue with the hardware,
and while we can fix it here for blits done by the driver, user
shaders writing outside the range of the destination bit size will
have the same issue and we probably don't want to add code to clamp
every single render target write in every shader with integer format.

Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
