This speeds up dumping make variables from ~380ms using make to ~220ms
using ckati. It also means that we're consistently using the same parser
for builds (with the same .KATI_READONLY/etc extensions).
envsetup.sh (lunch) / other scripts still use make, changing those to go
through soong_ui will be a future change.

Instead of pairing the reading of CleanSpec.mk files with the reading of
Android.mk files, split them into separate, individually cachable steps.
This way we only read Android.mk files once after a clean/sync. We'll
still read the CleanSpec.mk files multiple times, but that's
significantly faster than reading all the Android.mk files.
This adds about 50ms if kati doesn't need to reread the CleanSpec.mk
files. Reading all the CleanSpec.mk files takes about a second.

Wrap os/exec.Cmd to use our Context and Config interfaces for automatic
logging and error handling. It also simplifies environment modification
based on the Config's environment.
This also adds sandboxing on Macs using sandbox-exec. A simple profile
is provided that only logs on violations, though multiproduct_kati on
AOSP has no violations. This isn't applied to ninja, only make / soong /
kati to start with. I measured <5% time increase in reading all
makefiles, and no noticable difference when kati doesn't regenerate.
I'd like to spin up a process to dump violation logs into our log file,
but the log reporting changed over the range of Mac versions that we
support, so that's going to be more complicated. Opening Console.app
works in all cases if you're local -- just search/filter for sandbox.
Linux sandboxing will be implemented later -- the sandbox definition is
opaque enough to support a different implementation.
