bench/cli: extend --extrinsic name filtering

[ggwpez]

Current Situation

The bench-cli cannot be instructed to run more than one specific case per pallet.
This would be useful to have when trying to debug specific cases where others take really long to run, eg. in paritytech/substrate#10644.

Proposed Change

Make --extrinsic accept a comma separated list (done in paritytech/substrate#10677) or a regex such that ext1, ext2 or ext1|ext2 resp. would be valid.

A more advanced version could even allow filtering the whole "pallet.case" string for cross-pallet selection.

@ggwpez attempted this issue, kindly look at my solution in the PR.

paritytech/substrate#10677 implemented the list part, leaving this issue open since the regex could still be relevant.

Hello @ggwpez what is the regex supposed to specifically do asides from the comma separation that the other PR did?

It would allow for more advanced filtering. But the list approach is good enough for now, just wanted to keep track of it.

Alright @ggwpez when you ascertain what the advance filtering would be then i am willing to pick it up and implement so as to close out this issue.
