Using the have_neon boolean to enable NEON code means we have to either
fully enable it or fully disable it. When using -Dneon=runtime, ideally
only the parts that support runtime checks would be built for NEON, and
those that don't would be built without NEON. Though, there are no
longer any runtime checks for NEON anywhere, so it's equivalent to 'no'
with a warning.
In general, we should use have_* variables to indicate compiler support,
and *_opt options to choose if and how we want to utilize that. Use
neon_opt to control NEON compilation and avoid modifying have_neon which
now would fully refer to compiler support.

Trying to link both aecm/aecm_core_mips.cc and aecm/aecm_core_c.cc into
the same library results in an error because they both try to implement
webrtc::WebRtcAecm_ProcessBlock():

The MIPS-specific file is a replacement for the other, unlike the NEON
case. Don't add the default implementation unconditionally, add it only
for non-MIPS builds.

Ongoing fixes and improvements, transient suppressor is gone. Also,
dropping isac because it doesn't seem to be useful, and is just build
system deadweight now.
Upstream references:

Some API deprecation -- ExperimentalAgc and ExperimentalNs are gone.
We're continuing to carry iSAC even though it's gone upstream, but maybe
we'll want to drop that soon.
Since we cannot rely on the API to be stable upstream, let's start
making the pkg-config, library, and include dir have a version suffix.
This will allow different downstream projects depending on us to
independently switch versions without packagers having to jump through
hoops.
This new lib contains the bare minimum to implement an iSAC encoder and
decoder.
The webrtc files have been copied from the revision as the existing
imported files (c8b569e0a7ad0b369e15f0197b3a558699ec8efa).
