fix: fix MySQL and stripped_partial_indexes test issues (#5793)

Fixes:
- outdated snapshots missing `stripped_partial_indexes`
- missing `mariadb-mysql.js.wasm` for some MySQL tests that caused them
not to be run
- corrects some mysql tests to account for minor change in float
precision behavior (see prisma/prisma#29285)

## Summary by CodeRabbit

* **Tests**
* Expanded query engine testing to support MariaDB MySQL WASM target
compatibility alongside MySQL 8 configurations.
* Refactored test validation methodology to use programmatic assertions
for improved reliability.
* Updated schema describer test expectations to reflect current field
handling for index structures.
