mesa-pvr: convert bbappend into standalone alternative provider

There are some unobvious issues with adding PVR support to Mesa
via a bbappend:

1. We need to mark mesa package as machine-specific, due to
differences in builds between SGX, Rogue and software-rendering

2. We also need to then mark mesa package as providing safe
ABIs (EGL/GLES/GBM) in order for all generic dependent packages
to not be treated as machine-specific, allowing their re-use
across different machines of the same architecture

But doing the above alters the upstream mesa package and changes
its signatures even when not building for TI platforms, which is
a Yocto Project compliance violation.

In order to resolve this issue, convert Mesa bbappend, that adds
PVR support, into its own standalone alternative provider, called
mesa-pvr and allow selecting it with PREFERRED_PROVIDER settings.
