EmulatorPkg:Host: Port emulator to Xcode5

Xcode5 retired gdb, so this patch adds support for using, and loading symbols 
in, lldb.
The lldb script also supports dumping out the build generated guid database and 
it prints guids out with thier Cname if available. lldbefi.py also contains 
some EFI specific type formatters.

Unix/Host/X11IncludeHack is a symbolic link that is need to add the path for 
X11, since it is now an external package.
X11IncludeHack is a symbolic link to /opt/X11/include

To get X11 to work on a Mac you now have to install XQuartz: 
http://xquartz.macosforge.org

To fully work the -combine needs to be removed from the *_XCODE32_X64_CC_FLAGS 
in BaseTools/Conf/tools_def.template, this will be a separate commit.
