Update js-parser tests to match babel-parser

[sebmck]

js-parser is a fork of babel-parser. The code has diverged way too far to allow any sort of commit merging but the test fixtures are still valuable. packages/@romejs/js-parser/__rtests__/__rfixtures__/ should be updated with those from babel-parser/test/fixtures and the numerous bugs fixed that they uncover.

@sebmck Do I need to include the missing test fixtures from babel-parse ?.

[sebmck]

@pajaydev Yep. The options.json files will also need to be updated since they use options that Rome doesn't. Also removing any tests for syntax that Rome won't support such as some of the TC39 proposals.

@sebmck okay cool. Thanks 👍
