Merges the build settings for keyman64.dll vc++ project into the
keyman32.dll project, so they are both built from the same project, in
preparation for ARM support, to minimize repetition in the source tree.
There should be no material differences to the built libraries.
Also cleans up some noise in keyman32.vcxproj which made it easier to
verify the changes.
Fixes: #11904
