Add TStream descendant classes

[viniciusfbb]

Add TStream descendant classes: TMemoryStream, TFileStream, TBytesStream...

I know the project's focus is only GUI and not portability of all Delphi classes, but some RTL classes are fundamental for some GUI features, such as classes that implement TStream, which can be used in a TBitmap.LoadFromStream, for example.

Hi @viniciusfbb,

Thank you for your feedback.

A Delphi RTL extension module is under development. I expect our first release of those features very soon.

Yes, our plan is to have the P4D core where we only wrap the RTL. People who want to build console-based extension modules for Python don't need WrapVCL or WrapFMX. Then WrapVCL and WrapFMX will branch out with P4D core as a dependency. What do you think of that plan @viniciusfbb ?
