Tx_rollup: impose size limit on ticket contents in deposits

Context

Fixes #2588 (closed)

Add new protocol parameter tx_rollup_max_ticket_contents_size, set it to 10240 bytes.

When depositing tickets in apply.ml, check that the size of ticket contents does not exceed tx_rollup_max_ticket_contents_size using Script_typed_ir_size.node_size.

If it does, fail with new error Ticket_content_size_limit_exceeded.
