meson: ipa: Add mapping for pipeline handler to mojom interface file

Browse source 
Allow an arbitrary mapping between the pipeline handler and IPA mojom
interface file in the build system. This removes the 1:1 mapping of
pipeline handler name to mojom filename, and allows more flexibility to
pipeline developers.
