We already parse some boolean and integer values from named fw_cfg files (usually into PCDs), and we're going to cover more. Add a dedicated library for centralizing the parsing logic.

Replace the - QemuFwCfgFindFile(), - QemuFwCfgSelectItem(), - QemuFwCfgReadBytes(), - AsciiStrDecimalToUint64() sequence in the GetFirstNonAddress() function with a call to QemuFwCfgSimpleParserLib. This change is compatible with valid strings accepted previously.

…M_... The UPDATE_BOOLEAN_PCD_FROM_FW_CFG() macro currently calls the module-private helper function GetNamedFwCfgBoolean(). Replace the latter with QemuFwCfgParseBool() from QemuFwCfgSimpleParserLib. This change is compatible with valid strings accepted previously.

We don't distribute UEFI_DRIVER modules stand-alone that were built as part of an OVMF platform. OVMF's UEFI_DRIVERs are allowed to inherit platform dependencies. By enabling UEFI_DRIVERs to consume QemuFwCfgDxeLib, we can hook fw_cfg-based NULL class libraries into UEFI drivers, e.g. in order to set dynamic PCDs.

Add a minimal, NULL class library called "PxeBcPcdProducerLib" for setting the "PcdIPv4PXESupport" and "PcdIPv6PXESupport" PCDs of NetworkPkg, from fw_cfg. These PCDs control whether the UefiPxeBcDxe driver supports PXEv4 / PXEv6 boot. If a PXE version is disabled, the corresponding LoadFile protocol instance is not produced by UefiPxeBcDxe, and so EfiBootManagerRefreshAllBootOption() in UefiBootManagerLib does not generate corresponding *new* boot options either. (Existent boot options are not deleted.) Hook the library into the UefiPxeBcDxe driver. (The driver is already included from "NetworkComponents.dsc.inc", but we can list it again in the DSC file, for providing <LibraryClasses> overrides.) In OVMF, the PCDs could be set in PlatformPei too, but ArmVirtQemu does not have fw_cfg access in the PEI phase. Hence a NULL class library that can be linked into UefiPxeBcDxe. When listing the PCDs under [PcdsDynamicDefault], stick with the DEC default values. QEMU switches: -fw_cfg name=opt/org.tianocore/IPv4PXESupport,string=[yn] -fw_cfg name=opt/org.tianocore/IPv6PXESupport,string=[yn] The "opt/org.tianocore" prefix follows the "opt/RFQDN/" recommendation from QEMU's "docs/specs/fw_cfg.txt".
