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.

Record in parse table which actions can hide splits
...
Suppose a parse state S has multiple actions for a terminal lookahead symbol A.
Then during incremental parsing, while in state S, the parser should not
reuse a non-terminal lookahead B where FIRST(B) contains A, because reusing B
might prematurely discard one of the possible actions that a batch parser
would have attempted in state S, upon seeing A as a lookahead.
