meson: Rename variables storing headers lists

The list of public, IPA and internal header files are stored in three meson variables, named libcamera_api, libcamera_ipa_api and libcamera_headers respectively. The lack of uniformity is a bit confusing. Fix it by renaming those variables to libcamera_public_headers, libcamera_ipa_headers and libcamera_internal_headers.
