Add basic tests for PHP WASM grammar

[claytonrcarter]

Hi there. As mentioned in pulsar-edit#852 (comment), these are some example tests that I updated from my original work on the legacy PHP tree-sitter grammar.

The first commit runs, but most of the tests fail because it's trying to match the output of the TM grammar pretty closely. The second commit updates the tests to better match your code. eg I removed the punctuation scopes for semicolons, etc. Note that the second commit still has plenty of failures, because I found a few places where the new grammar maybe wasn't covering all of the bases. (eg ??=, % and instanceof).

The failing output I see is:

❯ ATOM_DEV_RESOURCE_PATH=~/src/Atom/pulsar/worktrees/add-php-grammar pulsar -d -t spec/wasm-tree-sitter-spec.js
...FF..F.FF.F.

Obviously happy to make any changes you'd like to see, or just to close this if you're not interested. Thank you!

I just added a few more tests for the cases I mentioned in pulsar-edit#852 (comment), eg readonly and opening and closing tags. Hope these help!

Sorry, I didn't get a notification when you opened this. Even though it's my own repo! I will look over it when I can, but feel free to remind me if it's been a week or so.

No worries! I just rebased this onto your latest branch. Depending on what you think of #2, I may retarget this at that branch to add coverage for my changes. Maybe just for my own sanity?!
