Add support for new SQL functions:

Function Description

uuid_generate_v5 Generates a UUID in the given namespace using the specified input name.
Add the is_superuser configuration parameter, which reports whether the current session is a superuser with admin privileges. This is part of the work to enable Role-based access control (RBAC) in a future release (#11579).
Add the ALTER ROLE command, as well as role attributes to the CREATE ROLE command. This is part of the work to enable Role-based access control (RBAC)(#11579).

It’s important to note that no role attributes or privileges will be considered when executing CREATE ROLE statements. These attributes will be saved and considered in a future release.

Function	Description
`uuid_generate_v5`	Generates a UUID in the given namespace using the specified input name.

Fix a bug that would cause the mz_sources and mz_sinks system tables to report the wrong size for a source after an ALTER {SOURCE|SINK} ... SET (SIZE = ...) command.
