**Problem:** After `ts_parser_parse_with_options()`, the parser options
are still stored in the parser object, meaning that a successive call to
`ts_parser_parse()` will actually behave like
`ts_parser_parse_with_options()`, which is not obvious and can have
unintended consequences.
**Solution:** Reset to empty options state after
`ts_parser_parse_with_options()`.
* 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
**Problem:** When resetting the parser during subtree balancing, an
error is thrown:
```
parser.c:2198: ts_parser_parse: Assertion `self->finished_tree.ptr' failed.
```
**Solution:** Reset `canceled_balancing` to false in
`ts_parser_reset()`.
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.

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.
* In WASM, use a custom, simple malloc implementation that lets us
expicitly reset the heap with a new start location.
* When a WASM call traps or errors, propagate that as a parse failure.
* Reset the WASM heap after every parse.

Replace non-mutating `ts_parser_wasm_store` function with
`ts_parser_take_wasm_store`, which removes and returns the wasm
store, in order to facilitate single ownership.
