x86/tdx: Add more registers to struct tdx_hypercall_args
struct tdx_hypercall_args is used to pass down hypercall arguments to
__tdx_hypercall() assembly routine.
Currently __tdx_hypercall() handles up to 6 arguments. In preparation to
changes in __tdx_hypercall(), expand the structure to 6 more registers
and generate asm offsets for them.
