tests: Add ResumableUpdaterTest.
This is a stress test that instantiates multiple testcases that
interrupt a BBOTA update at every transfer command. Each testcase
asserts the last_command_file after the interruption, verifies the
update resumability, then resumes the update and asserts the updated
image.
The transfer list in the testcase covers most of the transfer commands
(stash/free/move/bsdiff/zero/new), as well as some special pattern like
having duplicate stash ids.
This CL also addresses one issue in the updater code, by resetting the
stash_map before each run. The stash map should be valid only per
block_image_verify/block_image_update run. Having leftover may cause
issue in subsequent runs, in particular when calling block_image_verify
after a previous run of block_image_{update,verify}.
Test: Run recovery_component_test on marlin.
