Fix the logic for restoring previous span's colors to account for the
possibility of spans that don't change the color, such as in "<i><span
color='red'>...</span></i>foo". Previously, "foo" would always be
rendered black, because unwinding the attributes stack would encounter
an invalid color (which has r=g=b=0) and set it, disregarding and
preexisting attributes.
Because there's code in there that checks whether the attributes are
valid, we need to keep track of both the actually specified attributes
and the currently effective ones, and use the latter for restoration.
This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

VC6 has very poor support for template functions and in particular doesn't
understand explicitly choosing the type of the function to call so replace
template DoApplyToFont() function with FontModifier template class in
wxMarkupParserAttrOutput implementation.

wxMarkupText is a private class that implements generic handling of markup
strings, i.e. can measure them and render them onto a wxDC.
This class will be used for markup support in wxMSW wxButton.
Also add wxMarkupParserAttrOutput which will be useful for other wxMarkupText
implementations.
