Fix extended_dynamic_state2 tests

Fix extended_dynamic_state2 tests

Before this change alias assignment was only done for
promoted extensions. With this change search for aliases
is done for all extensions listed in extensions_data.txt.

This mainly fixes issue with tests for partially promoted
VK_EXT_extended_dynamic_state2. Three entrypoints that
were not promoted to vk1.3 must still use EXT when
vk1.2 implementation is tested.

This change also removes one duplicate from extensions_data.txt.
