OvmfPkg.dec: Add gOvmfFwCfgInfoHobGuid
Since TDVF has to measure FwCfg data from QEMU,
it is required to cache the data with measurement
in early phase. This can avoid changing the measurement
order when reading the FwCfg process, which depends
on multiple factors(depex, order in the firmware volume).

OvmfPkg/QemuFwCfgLib: Add FwCfg cache interface
Since TDVF needs to cache and measure FwCfg, it is required to
add an API to support cache with optional measurement and add some
internal interfaces to support cache in QemuFwCfgLib.
The new API is listed below:
QemuFwCfgInitCache()
The new Internal interfaces are listed below:
InternalQemuFwCfgCacheReadBytes()
InternalQemuFwCfgCacheSelectItem()
InternalQemuFwCfgCacheGetWorkArea()
InternalQemuFwCfgCacheResetWorkArea()
InternalQemuFwCfgItemCached()
InternalQemuFwCfgCacheReading()

OvmfPkg/QemuFwCfgLib: Support Cache FwCfg with optional measurement
OVMF uses FW_CFG_SELECTOR(0x510) and FW_CFG_IO_DATA(0x511) to
get configuration information from QEMU. From the security perspective
these information shall be measured before they're consumed.
This patch reads the FwCfg items and caches them in a GuidHob. In the
meanwhile these FwCfg items are measured as well. This is to avoid
changing the order when reading the FwCfg process, which depends on
multiple factors(depex, order in the Firmware volume).

Move QemuFwCfgSupported and QemuFwCfgDmaSupported to the struct

Additionally, change its name to QEMU_FW_CFG_WORK_AREA.
