Subject: [PATCH] Support explicit values in flag properties, add C# flags
 support

- Add support for explicit values in properties using `PROPERTY_HINT_FLAGS`
that works the same way it does for enums.
- Fix enums and flags in VisualScriptEditor (it wasn't considering the
explicit value).
- Use `PROPERTY_HINT_FLAGS` for C# enums with the FlagsAttribute instead
of `PROPERTY_HINT_ENUM`.
