Root cause: in the current tree, mach commands in mozilla-central output a
warning to stderr. The substitute-local-geckoview script was calling a mach
command and combining the stdout and stderr streams of the process, parsing
it as JSON. This warning is not JSON so the script crashed.

The crashing code was copied from settings.gradle:
  https://searchfox.org/mozilla-central/rev/b70bc09685763c44a8e56e4e04cb741fa020701a/settings.gradle#26

The code in settings.gradle does an intuitive thing - capture stderr separately
but only print it on subprocess non-zero exit value - so we also copy that
solution. I'm not sure what an appropriate place to store code shared between
these two files would be so I didn't try to deduplicate it.

This patch introduces a new field maven-artifacts which allows specifying a
list of maven artifacts that will be generated by a build and published to our
maven repository.

This allows us to split up GeckoView into separate maven packages.

Root cause analysis: in the changed implementation, the
substitute-local-geckoview script is called for every subproject in
android-components. Since this script calls a mach command, we're forced to wait
on the python interpretter for each a-c subproject (~113), which is very slow.

This patch addresses the problem by caching the output of loadMozconfig, which
calls the mach command, on the first run and using the cache on subsequent
invocations of the script.

Locally, with non-robust testing, I saw incremental build times decrease from
over five minutes to between 5-30 seconds.

This solution is ideal because it does not break downstream consumers. However,
it may not be the most correct solution because it's difficult to avoid writing
code that's not redundant if called multiple times. A more correct solution
would request that consumers call the script once and return a function for them
to call for each subproject.

This patch introduces a new local.settings field: mozilla-central.mozconfig.

This field can be used to set a custom mozconfig file for the gradle build (and
for Android Studio).

The environment variable MOZCONFIG will take precedence over what is defined in
local.settings to allow Gecko engineers to use multiple mozconfig files.

This patch adds a new GeckoView build variant dubbed "lite". We are in the
process of adding some optional dependencies to GeckoView that are needed by
Fenix (like Glean and Nimbus) which are likely not going to be used by anyone
else at Mozilla. To avoid bloating third party consumers, we provide a
geckoview-lite build that doesn't contain any optional dependency.

The min SDK version of GeckoView (non-lite) is being increased to 21 to match
Glean's min SDK. Given that Fenix's min SDK version is already 21 and that the
lite version's min SDK is still at 16 this change is safe to do and will not
incur in any loss of usability.
