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.
