hw/core: Only build guest-loader if libfdt is available 

Add a Kconfig entry for guest-loader so we can optionally deselect
it (default is built in), and add a Meson dependency on libfdt.

This fixes when building with --disable-fdt:

  /usr/bin/ld: libcommon.fa.p/hw_core_guest-loader.c.o: in function `loader_insert_platform_data':
  hw/core/guest-loader.c:56: undefined reference to `qemu_fdt_add_subnode'
  /usr/bin/ld: hw/core/guest-loader.c:57: undefined reference to `qemu_fdt_setprop'
  /usr/bin/ld: hw/core/guest-loader.c:61: undefined reference to `qemu_fdt_setprop_string_array'
  /usr/bin/ld: hw/core/guest-loader.c:68: undefined reference to `qemu_fdt_setprop_string'
  /usr/bin/ld: hw/core/guest-loader.c:74: undefined reference to `qemu_fdt_setprop_string_array'
  collect2: error: ld returned 1 exit status
