Problem: Macros (re)defined in `endian.h` conflict with system headers
on FreeBSD (at least).
Solution: Rely on system `endian.h` on OpenBSD, FreeBSD, NetBSD, and
DragonFly
Ref. https://github.com/mikepb/endian.h/issues/4
This allows users to bail parsing if an error was *definitely* detected
using the progress callback, as all possible stack versions have a
non-zero error cost.

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.
