MdePkg BaseLib NASM Thunk16: Initialize _16GdtrBase to 0
...
Previously we were setting it to the start of the GDT in the UEFI
driver's copy of BaseLib. This address is irrelavent, since the C code
will initialize it to the cooresponding address after the Thunk16 code
has been placed in low memory.
Additionally, initializing this was causing a link error for the
XCLANG toolchain.

MdePkg BaseLib NASM Thunk16: Use bits 16 for 16-bit code

By using 'bits 16', we can write code for 16-bit use the actual
assembly syntax rather than 'DB' and sometimes writing code with
seemingly incorrect operands because we know it will run correctly
when the processor is running in 16-bit mode.
