Riza Suminto b9b4a6d122 IMPALA-13330: Fix orc_schema_resolution in test_nested_types.py 
test_nested_types.py declare 'orc_schema_resolution' dimension, but does
not actually exercise it. None of the test actively inserting
'orc_schema_resolution' dimension value into
vector.get_value('exec_dimension').

This patch fix that issue by declaring 'orc_schema_resolution' option
using helper function add_exec_option_dimension() to automatically
insert it into 'exec_option' dimension. Test classes also reorganized to
reduce test skipping and deepcopy-ing.

Following are notable changes:
- Use 'unique_database' in test_struct_in_select_list to avoid collision
  during view creation.
- Drop unused 'unique_database' fixture in
  TestNestedCollectionsInSelectList.
- test_map_null_keys does not have 'mt_dop' dimension anymore since it
  only test how NULL map key are displayed.
- Created common base class TestParquetArrayEncodingsBase for
  TestParquetArrayEncodings and TestParquetArrayEncodingsAmbiguous. The
  latter does not run with 'parquet_array_resolution' anymore since that
  query option is set directly within parquet-ambiguous-list-modern.test
  and parquet-ambiguous-list-legacy.test files.
- Make ImpalaTestMatrix.add_dimensions() call
  ImpalaTestMatrix.clear_dimension() if given dimension.name is
  'exec_option' and independent_exec_option_names is not empty.

The reduction of test count are follows:
Before patch:
168 core tests, 571 exhaustive tests
After patch:
161 core tests, 529 exhaustive tests

Testing:
- Ran and pass test_nested_types.py in exhaustive exploration.
- Verified that no WARNING log printed by
  ImpalaTestSuite.validate_exec_option_dimension()
