Change subject: IMPALA-6724: Allow creating/dropping functions with the same
name as built-ins

IMPALA-6724: Allow creating/dropping functions with the same name as built-ins
This patch removes restriction on creating a function with the same name
as the built-in function. The reason for lifting the restriction is to
avoid a name clash when introducing new built-in functions. The patch
also fixes some inconsistent behavior when creating or dropping a function
when the name specified is fully-qualified or not.
Refer to the below tables for more information.
