Use NMTVDISPINFO instead of TV_DISPINFO in wxMSW code.

The latest w32api 4.0.3, used by MinGW project, still didn't manage to apply a
one line fix to define TV_DISPINFO correctly, so tweak our sources to avoid
using it.

See #15537.

Correct instructions for building wx applications with MSVC.

Use the correct $WXWIN/include/msvc path instead of the non-existing
$WXWIN/msvc.

Also mention that $WXWIN should actually be $(WXWIN) for MSVC.

Closes #16410.

Return correct string from wxEVT_TEXT wxComboBox events.

wxCommandEvent::GetString() could return empty string for the
programmatically-generated wxEVT_TEXT events from a wxComboBox.

Fix this by extending the on-demand string retrieval in wxCommandEvent to
wxComboBox as well (it was done only for wxTextCtrl).

Closes #3901.

Add support for paragraph spacing attribute to wxTextCtrl in wxMSW.

Use PFM_SPACEAFTER/PFM_SPACEBEFORE to implement support for them.

Closes #16417.

Fix handling of identical consecutive key events

Events generated programmatically may have the same timestamp as the previous
event, which caused them to be ignored on the assumption that they were the same
event being sent to a parent window. Fix this by detecting when a new event could
be generated by the event loop.
Closes #15802
