What does this PR do?
This PR optimizes the prisma test suite execution time.
Firstly it changes execPrismaGenerate from running 3 times per (config, version) pair to once in each of the without configuration, with out tracer initialization and with custom service describe blocks.
Since all the blocks use the same schema and version, the generated output is identical.
Added missing $disconnect() in integration test server files. The driver adpater connection was staying open and preventing Node.js from exiting, causing assertMessageReceived to wait until it's 30s default timeout.
Motivation
Unit tests: 18s → 6–7s
v7 PostgreSQL adapter integration tests: 10.5s/test → 530ms/test
v7 MSSQL adapter integration tests: 30.7s/test → 710ms/test
Full suite: from 4m → 2m
