[PATCH v3 0/9] Move Matrix class from libipa to libcamera

[Stefan Klug]

Hi all,

My upcoming dewarper series implements parametric lens dewarping inside
the rkisp1 pipeline. That code makes use of the Matrix class but lives
outside of the IPA. I suspect there will be more cases, where a matrix
is of good use inside libcamera.

This series movies the Matrix into libacmera/internal. As that gets
linked to the IPAs anyways, there are no negative effects for the IPAs.

This was tested on an imx8mp and the RaspberryPi.

Regards,
Stefan

Changes since v2:
- Collected tags
- Fixed comments from review
- Tested on RaspberryPi

Changes since v1:
- Split into smaller patches
- Replaced the initializer_list based constructor with a std::vector
  based one to align with Vector
- Dropped the Span based constructor as it is not used anywhere
