Add RBE metrics dump in Soong UI.

From aosp/1329396, the RBE metrics protobuf file is part of the
metrics uploading process. The RBE metrics protobuf file is
generated by running the bootstrap shutdown command. A new function
named DumpRBEMetrics was written in order to generate the RBE metrics
protobuf file before sending to the uploading process.

Bug: b/140638454
Test: * Unit test cases
      * Ran RBE build on my local host and verified the
        metrics protobuf file is created.
      * Ran non-RBE build after RBE build and verified that
        the previous metrics protobuf file was deleted.
