When CONFIG_INTEL_TDX_GUEST is not defined but CONFIG_UNACCEPTED_MEMORY=y is, the kernel fails to link with an undefined reference to tdx_accept_memory from arch_accept_memory. Provide a stub for tdx_accept_memory to fix the build for that configuration.

CONFIG_UNACCEPTED_MEMORY is also selected by CONFIG_AMD_MEM_ENCRYPT, and there are stubs for snp_accept_memory for when it is not defined. Previously this did not result in an error when CONFIG_INTEL_TDX_GUEST was not defined because the branch that references tdx_accept_memory() was being discarded due to DISABLE_TDX_GUEST being set.

And who unsets it now?
