libcamera: Move IPA headers from include/ipa/ to include/libcamera/ipa/

The IPA headers are installed into $prefix/include/libcamera/ipa/, but
are located in the source tree in include/ipa/. This requires files
within libcamera to include them with

 #include <ipa/foo.h>

while a third party IPA would need to use

 #include <libcamera/ipa/foo.h>

Not only is this inconsistent, it can create issues later if IPA headers
need to include each other, as the first form of include directive
wouldn't be valid once the headers are installed.

Fix the problem by moving the IPA headers to include/libcamera/ipa/.
