Casts from and to BIT type

[nickgerrets]

Solves #7640

Adds casting from numeric types, BOOLEAN type and BLOB type to BIT type and vice versa.
List of added casts:

• BOOLEAN
• TINYINT
• UTINYINT
• SMALLINT
• USMALLINT
• INTEGER
• UINTEGER
• BIGINT
• UBIGINT
• HUGEINT
• FLOAT
• DOUBLE
• BLOB

From bit to numerical types will throw an exception if there is not enough space to hold all the bits. From bit to boolean will convert the boolean value to become either 1 or 0 (true or false).
