meson: Add a configuration option to build IPAs

Browse source 
There can be multiple IPAs per pipeline-handler or platform.
They can live in-tree or externally linked. It is up to the vendor
whether to use in-tree IPA for a platform or provide it externally.
In the case of IPAs being external, building in-tree IPAs might be
futile hence, provide a clear and explicit mechanism to choose whether
to build the in-tree IPA for the platform or not.

By default, all in-tree IPAs are built when a matching Pipeline handler
is also enabled.
