fix: additions for prisma 6.17 and engineType = "client" compat

[jacek-prisma]

Porting some additions from the prisma mariadb adapter (I assume it should roughly map to tidb since it's MySQL). I haven't tested them carefully, but this makes it pass the prisma ecosystem tests for latest Prisma and engineType = "client".
