[IMP] owl-vision: syntax scripts, single quotes attributes and slot props highlight and switch below command

This commit adds the following:

- Syntax builder scripts to make syntaxes easier to read and edit
- Syntax highlight in single quote attributes
- Syntax highlight for slot props
- Basic syntax highlight for xpaths
- Added `Switch Below` command

This commit fixes the following:

- Using `Switch Besides` or `Switch Below` does not open a new panel if one was already open
- Fixed missing space in component's snippet indentation
