mysql type support

[zztkm]

I would like to add mysql as a supported target to give type hints other than Any to the generated models.

The following is an example with a pydantic model.

No mysql support:

# Code generated by sqlc. DO NOT EDIT.
# versions:
# sqlc v1.20.0
import pydantic
from typing import Optional


class Author(pydantic.BaseModel):
 id: Any
 name: Any
 bio: Optional[Any]

If support mysql !

# Code generated by sqlc. DO NOT EDIT.
# versions:
# sqlc v1.20.0
import pydantic
from typing import Optional


class Author(pydantic.BaseModel):
 id: int
 name: str
 bio: Optional[str]
