Move utf8len_tab definition to globals.h

Browse Source 
The existing code would cause utf8len_tab to be declared as non-extern
when main.cpp included globals.h as well as in mbyte.c.  This causes the
following warning

    Linking C executable ../../bin/nvim
    /usr/bin/ld: Warning: size of symbol `utf8len_tab' changed from 256 in CMakeFiles/nvim.dir/main.c.o to 320 in CMakeFiles/nvim.dir/mbyte.c.o

Moving the definition to globals.h and using INIT() ensures the array is
only defined in main.cpp and other places globals.h is included see an
extern declaration.
