Subject: [PATCH] Stop using make wrapper around soong_ui

Instead of running make -> makeparallel -> soong_ui, just run soong_ui.
Soong_ui now handles user-facing argument parsing.

The user visible changes should only be:
* Most `make` command line options are no longer supported. Many didn't
do anything useful before this change either.
* `-j` is now implied, so not specifying it will default to full
parallelism instead of a single-threaded build.
* `make` debug messages are removed:
  make: Entering directory ...
  make: Leaving directory ...
  make: *** [run_soong_ui] Error 1

We still support the make workflow for users that don't use envsetup.sh
-- the build servers primarily, but also various helper scripts. These
will be converted later.

Test: in $TOP; make nothing
Test: in $TOP/bionic; make (runs real make, fails w/no makefile)
Test: in $TOP; m nothing
Test: in $TOP; mm nothing
Test: in $TOP; mma nothing
Test: in bionic/libc; m nothing
Test: in bionic/libc; mm
Test: in bionic/libc; mma
Test: in $TOP; mmm bionic/libc
Test: in $TOP; mmma bionic/libc
Test: in bionic; mmm libc
Test: in bionic; mmma libc
Test: set WITH_STATIC_ANALYZER=1, repeat above
