Kirill A. Shutemov 75d090fd16 x86/tdx: Add unaccepted memory support
Hookup TDX-specific code to accept memory.

Accepting the memory is done with ACCEPT_PAGE module call on every page
in the range. MAP_GPA hypercall is not required as the unaccepted memory
is considered private already.

Extract the part of tdx_enc_status_changed() that does memory acceptance
in a new helper. Move the helper tdx-shared.c. It is going to be used by
both main kernel and decompressor.

  [ bp: Fix the INTEL_TDX_GUEST=y, KVM_GUEST=n build. ]
