Remove temporary fix for drawing check box in the wxPG edit mode with RTL layout

Since the issue is fixed (r77020) this hack is no longer necessary (see #16254).

Fix wxDC::DrawRectangle() when using RTL in wxMSW.

Extend the correct edge of the rectangle (always the physical right, not the
logical right) to fix off by one errors in RTL mode, affecting notably wxGrid.

See #16250.

Remove dynamic loading of GDI functions from wxMSW wxDC code.

All of these functions (AlphaBlend(), SetLayout(), SetWorldTransform(), ...)
are available in XP which is the minimally required version.

Fix markup on the preprocessor symbols documentation page.

Due to an apparent bug in Doxygen 1.8.2 (the version currently used for the
online documentation generation), using "@c __FOO__" not only renders __FOO__
in fixed width font, but also makes it bold (due to bad interaction with
Markdown support?), so use <tt>__FOO__</tt> instead to work around this.

And in one case, escape underscores explicitly (in __VISUALC7__) as they were
still interpreted, even inside <tt>.

Remove manual mirroring in RTL case from wxGrid code.

This is not necessary as wxDC already inherits RTL from the window itself and,
in fact, breaks the display when using RTL.

Closes #16250.

Link wxMSW with msimg32.lib now that AlphaBlend() is used statically.

Implicitly link msimg32.lib in when using MSVC and add it to MinGW (and
Borland) makefiles.

This should have been part of r77029.
