x86/tdx: Remove 'struct tdx_hypercall_args'
Now 'struct tdx_hypercall_args' is basically 'struct tdx_module_args'
minus RCX. Although from __tdx_hypercall()'s perspective RCX isn't
used as shared register thus not part of input/output registers, it's
not worth to have a separate structure just due to one register.
Remove the 'struct tdx_hypercall_args' and use 'struct tdx_module_args'
instead in __tdx_hypercall() related code. This also saves the memory
copy between the two structures within __tdx_hypercall().
