Removes incremental construction state entry and exit from AST edit operations.

The incremental construction state should not be entered for these edit operations
as such edits should trigger change propagation. The construction state should only
be entered when constructing the initial AST from constructors or when modifying the
AST during CTNA evaluation or similar.
