We are transitioning to a token-based API and will be removing the
old one.
Changes to use a thread state wait rather than reading the registers in
a loop to determine when the thread is actually suspended.

Packaged test running seems to be a ways off, but with a bit of path
fiddling in test_paths.cc we can actually use the paths where the tests
are copied, so do that instead to get all the tests re-enabled. The
setup in BUILD.gn should be mostly-useful once packaging is working as
all helper/data files will need to specified there anyway.
Also, attempted fix to flaky behaviour in
ProcessReaderFuchsia.ChildThreads exposed because the tests are now
being run. zx_object_wait_many() waits on *any* of the objects, not
*all* of them. Derp!
And finally, for the same test, work around some unintuitive behaviour
in zx_task_suspend(), in particular that the thread will not be
suspended for the purpose of reading registers right away, but instead
only "sometime later", which appears in pratice to be after the next
context switch. Have ScopedTaskSuspend block for a while to try to
ensure the registers become readble, and if they don't, at least fail
noisily at that point.

This implementation has some limitations as documented in the header,
however, threads must be suspended in order to use the register capture
debug API so this is somewhat useful for now in the context of
generate_dump.
Also, refactor some child-object retrieval helpers used in a few places.
