Add 'tensor' bit to commit_if and writeback_if
...
For use in the asynchronous tensor instruction. When 1'b1, sets/unsets
the inuse_tensor status bit in the scoreboard to signal
kickoff/completion of the asynchronous tensor op.

tensor: Test many-commit per execute with an FSM
...
Trick is to set commit_if.data.eop to 0, since the commit module only
signals instruction completion to VX_schedule if the eop bit is 1.
Otherwise it underflows the pending_instr buffer.
The same eop trick works for VX_scoreboard, which works around the
invalid rd writeback error.

Add more efficient dispatch_unit
...
Instead of having a single candidate to be considered for dispatch
(designated by 'batch_idx' counter), add a dispatch_unit variant that
considerse all `ISSUE_WIDTH dispatch signals and picks a valid one in a
round-robin manner.
This increases core utilization significantly due to better overlapping
of smem/tensor ops.
