Attachment: Bug 1748966 - Speed up bootstrap.

Currently, the bootstrap code from configure gets bootstrapped task info
from the taskgraph, and then invokes mach artifact toolchain which...
does the same again. That cumulatively wastes a noticeable amount of
time, especially on Windows.

So to avoid repeating this work that the configure side already did,
we do a little more on the configure side (resolution from index to
task-id), and just give a (task-id, artifact path) pair to mach artifact toolchain. The added code to mach artifact toolchain is
actually ironically very similar to the code that was removed in bug
1687594.

And now that mach bootstrap uses the configure code, it benefits from
this change as well.
