Switch to using preinstrumented android-all jars by default
These jars are equivalent to the regular android-all jars but have already
undergone default Robolectric invokedynamic instrumentation. The initial
versions have been published on MavenCentral here:
https://repo1.maven.org/maven2/org/robolectric/android-all-instrumented/
By using preinstrumented jars, tests can avoid having to perform the exact same
bytecode instrumentation each time a Robolectric Sandbox is initialized. This
process is slow and consumes a lot of CPU, especially in multi-SDK tests.
From our testing it decreases the median Roboelctric test process time by
approximately 10-12 seconds in a cloud environment (YMMV on workstations). For
things like TDD this can really make a difference.
The preinstrumented jars can be generated using:
`./gradlew :preinstrumented:instrumentAll`
Note, these have to be regenerated if something like AndroidInterceptors
changes, but that happens approximately once every 6-12 months. When that
happens we can switch CircleCI back to non-instrumented jars, or just bump the
preinstrumented version.
