[C++][Parquet] Generalize existing null bitmap generation

Right now null bitmap generation assumes only list nesting.  Generalize and refactor exisitn code without changing existing functionality to accept additional parameters to support arrow nested types:

1.  Repeated ancestor def level

2.  Null slot usage (for fixed size lists)

Review the existing null bitmap generation for list nesting and compare the requested behavior with pull request #8156. The work is done when repeated ancestor definition levels and null slot usage for fixed-size lists are supported without changing existing functionality.
