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).
