chore: remove query engine (#5685)

Remove the top level QE crates, SQL query connector and QE-specific code
from `query-core`, and move the crates used by QC to the
`query-compiler` directory.

Also removes the Node-API specific code from `driver-adapters` and
leaves only the Wasm implementation to be used by `schema-engine-wasm`.

Unused MongoDB query connector is left for future reference as we are
going to be porting that logic to QC.

Required for #5683.

Closes:
https://linear.app/prisma-company/issue/TML-1554/remove-query-engine-from-prisma-engines
