QLibraryInfo: Add isSharedBuild() function and deprecate qSharedBuild()

Now that there's QLibraryInfo::isDebugBuild(), it's better to also
have QLibraryInfo::isSharedBuild() at the same time. It's also a
very useful information about the current Qt build.
I think debug/release and static/shared are the most important
properties of a library, so it's better to have them both.

Deprecate the global function qSharedBuild() in favor of the newly
introduced QLibraryInfo::isSharedBuild().

As a drive-by, add the nodiscard attribute to both functions.

[ChangeLog][QtCore] Added QLibraryInfo::isSharedBuild() and deprecated
qSharedBuild().
