refactor(lsp): use File_Language instead of Linter_Options for Lintable_Document
Lintable_Document keeps track of a Linter_Options object. This will be problematic when we allow some linter options to be overwritten by a user quick-lint-js.config file. Refactor Lintable_Document to work with File_Language instead. Only create a Linter_Options object at the last minute.
