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

Expose lower stack nodes via pop_until() function
...
This callback-based API allows the parser to easily visit each interior node
of the stack when searching for an error repair. It also is a better abstraction
over the stack's DAG implementation than having the public functions for
accessing entries and their successor entries.

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.
