Add a `Bytes` property to `TVIBinResource` to access version info data

[delphidabbler]

Having read access to version info data without going via a stream would be very useful.

The property (or method) should copy all version info data to a TBytes array.

A matching ability to load version info data via a byte array would also be useful.

Could this be implemented using Delphi's TBytesStream? This could be adapted to IStream using TStreamAdapter.

That way the existing stream loading code could be used.

⚠️ I seem to recall some problems with TBytesStream setting it's size to a multiple of its buffer size rather than the actual number of bytes in the byte array. I may be wrong, but be careful!
