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 https://github.com/prisma/prisma-engines/pull/5683.
