configs: amd: Enable capsule update and DFU support

Enable EFI capsule update configs (EFI_RUNTIME_UPDATE_CAPSULE,
EFI_CAPSULE_ON_DISK, EFI_CAPSULE_ON_DISK_EARLY, and
EFI_CAPSULE_FIRMWARE_RAW) and DFU backend configs (DFU_MMC,
DFU_MTD, DFU_SF) for the Versal Gen 2 virtual platform. Increase
SYS_MALLOC_LEN, SYS_MALLOC_F_LEN and SYS_INIT_SP_BSS_OFFSET to
accommodate capsule update buffer requirements.
