Multiple files in libcamera are missing SPDX headers. Add them with the
following licenses:
- CC-BY-SA-4.0 for documentation
- CC0-1.0 for build system, development tool configuration files and
TODO lists, as we consider them non-copyrightable, and for example
configuration files to facilitate their use
- BSD-2-Clause for a file copied from the Raspberry Pi tuning tool (and
add the corresponding copyright information)
While at it, add a missing blank line to
src/libcamera/pipeline/virtual/README.md.
