Introduces a new function that takes in a supertype symbol and returns
all associated subtypes. Can be used by query.c to give better errors
for invalid subtypes, as well as downstream applications like the query
LSP to give better diagnostics.
When collecting captures, we were treating unfinished ones as definite
even if they had pending immediate steps that weren't yet satisfied. Now
we only mark a capture as definite if the pattern is guaranteed and
there are no pending immediate steps to check.
When a pattern appears under a wildcard parent (like "(_ (expr))"), we
were incorrectly marking it as infallible. The parent_pattern_guaranteed
flag only means the pattern will match after finding the right wildcard
parent, not that any wildcard parent will work.
Previously, when a pattern was marked as the last child in a query, its
alternatives weren't marked similarly, causing incorrect matching
behavior. Now, the `last_child` status is properly propagated through
all alternatives.

WASI doesn't support `dup(2)` system call, so we cannot implement the
`print_dot_graph` and `print_dot_graphs` functions with exactly the same
semantics as in other platforms.
Previously, `child_containing_descendant` would return `null` when
called on a node's direct parent. In my opinion, this doesn't make much
sense; it seems like a node would contain itself. This (breaking)
commit changes the function so that it can return direct children.
This issue shows up when we have a zero-width token that is the target
descendant node, previously the previous sibling would be returned as
the child that contains the descendant, which is incorrect.
Currently, if a predicate is hard to match on the Rust side, a sizable
query against a very large file can take forever, and ends up hanging.
This commit adds an API function `ts_query_cursor_set_timeout_micros` to
limit how long query execution is allowed to take, thereby negating the
chance of a hang to occur.
