Add a new living document presenting a matrix of image processing
feature support across all currently supported platforms in libcamera.

This will hopefuly help in answering questions like is HDR supported
with Software ISP or is Auto Focus supported on Raspberry Pi?

This matrix will be regularly updated as new features and platforms are
added.

Just a small thing, I think it would be better to use footnotes for these. E.g.

   Renesas V2H/V2N [#renesas_v2]_

in the table and then later:

.. rubric:: Footnotes

.. [#renesas_v2] Based on ARM's Mali C55 ISP, therefore easily extendable to other SoCs that integrate that ISP
.. [#softisp_cpu] lorem ipsum dolor sit amet...

This makes them clickable and everything.

Also while testing these changes, I found that editing of this table is quite time
consuming because everything apparently has to be aligned. I found that there is a
thing called `csv-table`, which can even load the content from an external file, so
I just wanted to bring that up as an alternative, which requires less strict formatting
of the data. But it's probably not worth the change now.

I also tried to make the first row and column "sticky" (in CSS parlance) for vertical
and horizontal scrolling, but sadly haven't found a way.

Neat, will do in v6.

Yeah, I had initially chosen the rST list table instead to make it easy to

CSV would be best of both worlds indeed, will look into that separately

+.. note::
+
+    **\*** Based on ARM's Mali C55 ISP, therefore easily extendable to other
+    SoCs that integrate that ISP
+
+    **\*\*** CPU-based image processing, therefore extendable to any platform.
+    Currently the following are supported:
+
+    * Intel 11th-14th Gen (IPU6)
+    * Intel 15th Gen (IPU7)
+    * Texas Instruments J7x/AM6x
+    * Qualcomm Snapdragon (CamSS)
+
