x86/virt/tdx: Define TDX supported page sizes as macros

TDX supports 4K, 2M and 1G page sizes.  The corresponding values are
defined by the TDX module spec and used as TDX module ABI.  Currently,
they are used in try_accept_one() when the TDX guest tries to accept a
page.  However currently try_accept_one() uses hard-coded magic values.

Define TDX supported page sizes as macros and get rid of the hard-coded
values in try_accept_one().  TDX host support will need to use them too.
