[DML] Add target attributes parsing for UPSERT and REPLACE

[am357]

Requested Solution/Feature

• The current parsing of UPSERT INTO and REPLACE INTO does not support parsing of [ ( <attr name> [, <attr name> ]... ) ] in the following grammar; this issue is to track the effort for making this addition.

<upsert statement> ::= UPSERT INTO <table name> [ AS <alias> ] 
    [  ( <attr name> [, <attr name> ]... ) ]
        <values>
        
<replace statement> ::= REPLACE INTO <table name> [ AS <alias> ] 
    [  ( <attr name> [, <attr name> ]... ) ]
        <values>

Describe Alternatives

N/A.

Additional Context

N/A.

DoD (Definition of Done)

The following tests pass:

REPLACE INTO foo (a, b) SELECT bar.id, bar.name FROM bar

UPSERT INTO foo (a, b) SELECT bar.id, bar.name FROM bar

REPLACE INTO foo (a, b, c) VALUES (2, DEFAULT, 4)

UPSERT INTO foo (a, b) VALUES ('bar', DEFAULT)
