feat: add whereIn for SelectBuilder

[LuisDuarte1]

This API abbreviates the usage of (field, test) IN (VALUES (?, ?), (?, ?)) in where conditions by dynamically constructing this query dynamically depending on the number of fields given and the length of values given.

This makes it really easy to build dynamic queries that filter by multiple status:

db.select('employee').whereIn('role', ["eng", "hr", "sales"])

It will generate something like this sql:

SELECT * FROM employee WHERE (role) IN (VALUES ('eng'), ('hr'), ('sales));

This is SQL syntax supported by both postgres and SQLite (therefore D1 and DOs too)

Or we can use this for multiple fields at the same time:

db.select('employee').whereIn(['role', 'team'], [["eng", "workers"], ["eng", "workflows"]])

Also, we make the arguments to whereIn typesafe:

• whereIn fields only support a string or a array of strings
• whereIn values are checked against the fields type (if the field type is a string, means that we can only pass a Primitive list, otherwise, if the field type is an array of strings, means that we must pass a list of a list of primitives)
