The MIPS-specific source for vector scaling operations fails to build on
Debian's mips64el:

/tmp/cc7UGPkY.s: Assembler messages:
/tmp/cc7UGPkY.s:57: Error: opcode not supported on this processor: mips64r2 (mips64r2) `extrv_r.w $3,$ac0,$8'
ninja: build stopped: subcommand failed.
The EXTRV_R.W instruction it uses is part of DSP extensions for this
architecture. In signal_processing_library.h, this function's prototype
is guarded with #if defined(MIPS_DSP_R1_LE). Guard the implementation
like that as well to fix the error.

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:
Version: 131.0.6778.200
WebRTC: 79aff54b0fa9238ce3518dd9eaf9610cd6f22e82
Chromium: 2a19506ad24af755f2a215a4c61f775393e0db42
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.
Corresponds to upstream commit 524e9b043e7e86fd72353b987c9d5f6a1ebf83e1
Update notes:
* Moved src/ to webrtc/ to easily diff against the third_party/webrtc
in the chromium tree
* ARM/NEON/MIPS support is not yet hooked up
* Tests have not been copied
