Add support for DML with properties in engine + Add support for branching in Iceberg

[ebyhr]

Description

The 1st commit allows properties after the target table name in DML:

    | INSERT INTO qualifiedName ('@' branch=string)?
       columnAliases? rootQuery                                        #insertInto
    | DELETE FROM qualifiedName ('@' branch=string)?
         (WHERE booleanExpression)?                                    #delete
    | UPDATE qualifiedName ('@' branch=string)?
        SET updateAssignment (',' updateAssignment)*
        (WHERE where=booleanExpression)?                               #update
    | MERGE INTO qualifiedName (AS? identifier)? ('@' branch=string)?
        USING relation ON expression mergeCase+                        #merge

Avoided session property approach because users may forget the current branch and modify unexpected branch.

The 2nd commit introduces branching support and adds the following procedures in Iceberg connector:

• ALTER TABLE table EXECUTE create_branch(name)
  • creating a new branch
• ALTER TABLE table EXECUTE drop_branch(name)
  • removing a branch by name
• ALTER TABLE table EXECUTE fast_forward(from, to)
  • performs a fast-forward of from up to the to snapshot if from is an ancestor of to.

TestIcebergBranching uses that new syntax and procedures.

Relates to #12844
