Bound extrinsic inputs

[4meta5]

Closes #662

Extrinsics for which unbounded inputs were bounded in this PR:

• tasks (submit_result)
• shards (commit)
• network (register_network)
• dmail (send_email)

TODOs:

• use wrapper structs instead of type aliases Update subxt to bounded types #1212
• update tc-subxt 8ce3e13
• update chronicle f6a6f41
• update chronicle mock and tests 06918f6
• update tc-cli 252cf6c
• re-run benchmarks => update weights

Follow-ups:

• Runtime tests to ensure bounded extrinsic inputs #1192
• Investigate benchmarks for all weight functions with unused inputs #1216

Hi Thanks for taking tihs on! One update that dmail pallet needed regarding bounding data is that their to and path field will always be of 64 length. So we can bound it to that fixed length.

ok, looks fine

ok all the type aliases need to be changed to wrapper structs because of subxt metadata constraints according to david. #1212
