Jim Mussared b22abcdbbe extmod/uasyncio: Handle gather with no awaitables.
This previously resulted in gather() yielding but with no way to be
resumed.

Damien George 28e7e15c0a extmod/uasyncio: Fix bug with task ending just after gather is cancel'd.
This fixes a bug where the gather is cancelled externally and then one of
its sub-tasks (that the gather was waiting on) finishes right between the
cancellation being queued and being executed.

Damien George ef1c2cdab0 tests/extmod/uasyncio_gather: Make double-raise gather test reliable.
This double-raise test could fail when task[0] raises and stops the gather
before task[1] raises, then task[1] is left to raise later on and spoil the
test.

Damien George 90aaf2dbef extmod/uasyncio: Fix gather cancelling and handling of exceptions.
The following fixes are made:
- cancelling a gather now cancels all sub-tasks of the gather (previously
  it would only cancel the first)
- if any sub-task of a gather raises an exception then the gather finishes
  (previously it would only finish if the first sub-task raised)

Fixes issues #5798, #7807, #7901.

Damien George c4935f3049 tests/extmod: Add uasyncio tests.
All .exp files are included because they require CPython 3.8 which may not
always be available.
