* relax Sized bound for Signers in Transaction and Client
* also relax Sized bounds in client, runtime, thin-client and tpu-client
* add tests for using non-sized transaction signers
* fix macro for thin_client vs ?Sized
* move tests to transactions, add Sized relaxation to mut macro
* fix clippy warning
* get rid of unnecessary imports
1. replace hardcoded loaded accounts data size limit with compute budget instruction;
2. new transaction error for invalid account data size limit
3. test requested limit with combination of features and transactions
- Add new compute-budget instruction to set transaction-wide accounts data size limit
- Set default accounts data limit to 10MB, and max to 100MB, per transaction;
- Add getters to make changing default and/or max values easier in the future with feature gates;
- added error counter for transactions exceed data size limit

* Add a SanitizedMessage type that caches writable accounts indexes
* Add is_writable_account_cache to both SanitizedMessage variants, cache is initialized in constructors
* Fixup typo
* Add new feature
* Add new TransactionError

* Review comments: combine process_result success behavior; log and metrics before feature activation
* Fix tests that assume rent-exempt accounts are okay
* Remove test no longer relevant
* Remove native/sysvar special case
* Move metrics submission to report legacy->legacy rent paying transitions as well
