This is to deduplciate uploads and downloads when running builds with
RBE. Especially useful for certain Java / R8 / D8 actions that have JAR
files as common inputs.

The current rbesetup.sh has to be source from the root directory
of the checked out repo since it has a relative path to the sourced
build/envsetup.sh script. A function was written in rbesetup.sh
script to source the rbesetup.sh script anywhere inside of a
checked out repo. Added additional error checking to validate
the envsetup.sh is available and not to continue sourcing the script
if envsetup.sh script is not found.
Fixes: b/169438960
Test: Sourced the rbesetup script from
* external directory
* inside of a symlink
* outside of repo (sourcing fails which is correct)
* root repo

ran "use_rbe m" and that worked.
