add: UNSIGNED numeric data types for MySQL

[rapsealk]

Hi. I found that type suggestion does not provide any unsigned types, which gave me a little inconvenience.

I found the list of types that support unsigned option at https://dev.mysql.com/doc/refman/8.0/en/numeric-type-syntax.html.

To add a type to autocomplete, a list is added from the following file.

Sorry, it seems that unsigned keyword is an attribute, not a type. Would it be okay to add it to PrimitiveType like..

export type PrimitiveType =
  | 'int'
  | 'int unsigned'
...

or add another field to DataTypeHint like below?

export interface DataTypeHint {
  name: string;
  primitiveType: PrimitiveType;
  unsigned: boolean;
}

Since this type is for cordegenerate mapping purposes, there is no need to divide it in detail. I don't need it right now, so I think I can use the int
