fix(mysql): validate parameter count for prepared statements (#3857)
* fix(mysql): validate parameter count for prepared statements

Add validation to ensure the number of provided parameters matches the
expected count for MySQL prepared statements.
This prevents protocol errors by returning an error if the counts do not match before sending
the statement for execution.

* refactor(mysql): use err_protocol macro for error creation

Replace direct Error::Protocol(format!()) calls with err_protocol!
macro in MySQL connection executor.

* test(mysql): add parameter count validation tests

- Add test for too few parameters provided to query
- Add test for too many parameters provided to query
- Add test for parameters provided when none expected
- All tests verify Error::Protocol is returned for mismatches

Covers cases for issue #3774 parameter validation fix.

Merge of #3427 (by @mpyw) and #3614 (by @bonsairobo) (#3765)
* feat: Implement `get_transaction_depth` for drivers

* test: Verify `get_transaction_depth()` on postgres

* Refactor: `TransactionManager` delegation without BC

SQLite implementation is currently WIP

* Fix: Avoid breaking changes on `AnyConnectionBackend`

* Refactor: Remove verbose `SqliteConnection` typing

* Feat: Implementation for SQLite

I have included `AtomicUsize` in `WorkerSharedState`. Ideally, it is not desirable to execute `load` and `fetch_add` in two separate steps, but we decided to allow it here since there is only one thread writing. To prevent writing from other threads, the field itself was made private, and a getter method was provided with `pub(crate)`.

* Refactor: Same approach for `cached_statements_size`

ref: a66787d36d62876b55475ef2326d17bade817aed

* Fix: Add missing `is_in_transaction` for backend

* Doc: Remove verbose "synchronously" word

* Fix: Remove useless `mut` qualifier

* feat: add Connection::begin_with

This patch completes the plumbing of an optional statement from these methods to
`TransactionManager::begin` without any validation of the provided statement.

There is a new `Error::InvalidSavePoint` which is triggered by any attempt to
call `Connection::begin_with` when we are already inside of a transaction.

* feat: add Pool::begin_with and Pool::try_begin_with

* feat: add Error::BeginFailed and validate that custom "begin" statements are successful

* chore: add tests of Error::BeginFailed

* chore: add tests of Error::InvalidSavePointStatement

* chore: test begin_with works for all SQLite "BEGIN" statements

* chore: improve comment on Connection::begin_with

* feat: add default impl of `Connection::begin_with`

This makes the new method a non-breaking change.

* refactor: combine if statement + unwrap_or_else into one match

* feat: use in-memory SQLite DB to avoid conflicts across tests run in parallel

* feedback: remove public wrapper for sqlite3_txn_state

Move the wrapper directly into the test that uses it instead.

* fix: cache Status on MySqlConnection

* fix: compilation errors

* fix: format

* fix: postgres test

* refactor: delete `Connection::get_transaction_depth`

* fix: tests
