sqlite: validate aggregate() name and options

[araujogui]

database.aggregate() cast its arguments without checking their types:

• db.aggregate() threw a raw V8 TypeError (no code)
• db.aggregate(123, {...}) silently registered a function named "123"

Both now throw ERR_INVALID_ARG_TYPE, matching database.function().
