Fix cases where error recovery could infinite loop (#4257)
* Rename corpus test functions to allow easy filtering by language

* Use usize for seed argument

* Avoid retaining useless stack versions when reductions merge

We found this problem when debugging an infinite loop that happened
during error recovery when using the Zig grammar. The large number of
unnecessary paused stack versions were preventing the correct recovery
strategy from being tried.

* Fix leaked lookahead token when reduction results in a merged stack

* Enable running PHP tests in CI

* Fix possible infinite loop during error recovery at EOF

* Account for external scanner state changes when detecting changed ranges in subtrees

bbc1370dd5 feat(lib)!: treat nodes' end ranges exclusively in goto_first_child_for_{byte,point}
This goes back on #1640, because now cursors are bi-directional, and
going to the previous sibling is simple.

919e9745a6 Add ts_tree_cursor_goto_first_child_for_point function
This function (and the similar `ts_tree_cursor_goto_first_child_for_byte`)
allows you to efficiently seek the tree cursor to a given position,
exploiting the tree's internal balancing, without having to visit
all of the preceding siblings of each node.

e13581b041 Fix build with GCC 11
It seems redundant to array_init() when the structure is zeroed already
in the static assignment. But probably the fact that this code juggles
between TSTreeCursor and TreeCursor, without using a union, leaves the
compiler unable to tell that it's been initialized.

186b08381c Terminate failed query matches before descending whenever possible
When iterating over captures, this prevents reasonable queries from 
forcing the tree cursor to buffer matches unnecessarily.
