Consider multiple error repairs on the same path of the stack

This changes the API to the stack_iterate function so that you can pop

Merge equivalent stacks in a separate stage of parsing
...
* No more automatic merging every time a state is pushed to the stack
* When popping from the stack, the current version is always preserved

Return a TreeArray from ts_stack_pop

Since the capacity is now included in the return value, the buffer
can be reused in the ts_parser__accept function. Also, it's just
cleaner to use Array consistently, rather than a separate buffer
and size.
