The RAM of TDX VM can be classified into two types: - TDX_RAM_UNACCEPTED: default type of TDX memory, which needs to be accepted by TDX guest before it can be used and will be all-zeros after being accepted. - TDX_RAM_ADDED: the RAM that is ADD'ed to TD guest before running, and can be used directly. E.g., TD HOB and TEMP MEM that needed by TDVF. Maintain TdxRamEntries[] which grabs the initial RAM info from e820 table and mark each RAM range as default type TDX_RAM_UNACCEPTED. Then turn the range of TD HOB and TEMP MEM to TDX_RAM_ADDED since these ranges will be ADD'ed before TD runs and no need to be accepted runtime. The TdxRamEntries[] are later used to setup the memory TD resource HOB that passes memory info from QEMU to TDVF.
