[PG] Improve default value generation for array columns

[L-Mario564]

Addresses #2621, #2709, #2432, #2334, #2224, #1003 & #1564.

This PR aims to improve the way Drizzle Kit generates the default value for array columns, successfully converting a TS array into a string that represents it in SQL.

Thanks a lot, @L-Mario564! To ensure that all the tickets from the list are closed, please add test cases for all the issues

• for example #2709 has a problem with the default in enums, but I can't see a test case for the enum type
• for #1003 it's uuid type
• #1564 also has a enum in example
