CrOS intends to provide a Bazel executable for our users in
chromite/bin/bazel in our tree. We'd like the "bazel" command in
depot_tools to call this executable.
This adds a new launcher to depot_tools which searches for that bazel
executable when located inside of a ChromiumOS checkout, and executes
it. When located outside of a ChromiumOS checkout, this launcher
"disappears", searching elsewhere in the PATH for another Bazel
executable.
Since other teams using depot_tools may want to start using Bazel in
the future, this launcher is intended to have shared ownership: other
teams are welcome to come add their search functions to the launcher
if they require the same functionality as us.
