ipa: meson: Allow nested IPA directory structures

The current IPA build files require a flat directory structure for the
IPAs. Modify the build files to remove this restriction and allow a
directory structure such as:

src/ipa
  |- raspberrypi
      |- common
      |- cam_helpers
      |- controller
      |- vc4
  |- rkisp1
  |- ipu3

where each subdir (e.g. raspberrypi/common, raspberrypi/cam_helper) has
its own meson.build file. Such a directory structure will be introduced
for the Raspberry Pi IPA in a future commit.
