Refactor custom data support.

Changes:

- Feature: HTML attribute completion documentation
- Rename: tagProvider -> dataProvider
- API: Now in sync with CSS LS API
- HTMLTagSpecification converted to serializable plain data structure
so does attributes and attribute values
- Remove Angular1/Ionic1 support
- Remove i18n for HTML tags, and manage them in a plain JSON-like file because
  - We don't have i18n support in LSP yet
  - There's no translation yet
  - The JSON-like file is typed and can be easily mainaintaed
  - We'll start pulling data from W3C HTML spec and MDN to do features
  such as short descriptions, browser support table adn syntax. Such
  plain JSON-like files are easy to auto-generate.
  - Unblocks #12, #30, #44

Fixes:

- Fix microsoft/vscode#2784
- Part of microsoft/vscode#63955 (no CompletionItem.documentation for attr value yet)
