bitbake: runqueue: add option to run all tasks in specific build target

For example:

$ bitbake core-image-minimal --runall unpack
...
NOTE: Tasks Summary: Attempted 326 tasks of which 88 didn't need to be rerun and all succeeded.

$ bitbake core-image-minimal --runall patch
NOTE: Tasks Summary: Attempted 453 tasks of which 332 didn't need to be rerun and all succeeded.

This can replace fetchall as well:
$ bitbake core-image-minimal --runall fetch
NOTE: Tasks Summary: Attempted 135 tasks of which 119 didn't need to be rerun and all succeeded.

(Bitbake rev: 7c0fa6ba66cdb956b37d94055307cde857633df9)
