[Enhancement] "GetProperty" and others methods

[Igoorx]

Currently, Reflection is lacking methods to get properties. Even though there's a mPropertyDataCount & mPropertyDataPtr in Type.bf, but there's no method that uses these fields.

Example: https://docs.microsoft.com/en-us/dotnet/api/system.type.getproperty?view=net-5.0

Edit: Beef is also lacking the "GetInterface" methods Example: https://docs.microsoft.com/pt-br/dotnet/api/system.type.getinterfaces?view=net-5.0
