src/hb-common.cc: Fix build on older Visual Studio

Visual Studio only supported strtof() from Visual Studio 2013 onwards, so
use strtod() instead to do the operation, which should do the same thing,
sans going to a double, not a float.

Visual Studio builds: Fix Introspection when UCDN enabled

The sources in src/hb-ucdn and not included correctly into the NMake
Makefiles, as we need their explicit relative location as we pass all the
sources we used into the introspection scanner.  This was not an issue
before as we excluded the UCDN sources in the build when we enabled
introspection (meaning GLib is enabled), but since we default on using
UCDN on all builds unless explicitly disabled, we need to deal with this.

This did not affect builds using UCDN without introspection due to the use
of NMake batch rules.

Fix this by creating a NMake Makefile module on-the-fly with the correct
subdir info, and using that list in there instead.

Update Visual Studio builds for UCDN usage

We now use UCDN by default, so make it so in the build files; however
don't hardcode HAVE_UCDN as one may still opt not to use it (but pass
it in as a CFLAG unless one explicitly disables UCDN by using NO_UCDN=1
on the NMake command line).

Note that we are not blocking builds where UCDN is disabled along with
GLib and ICU, as that will trigger a build error anyways which will tell
the user what needs to be done to remedy this.
