When TPM PCR0 measurements fail, query if secure boot is available and enabled
...
If the measurements are missing but it's a UEFI system, it's a good indication
that the user has secure boot turned off.
Notify the user on the UEFI device through a non-fatal `UpdateMessage`
To accomplish this, move fu-uefi-vars into the plugin library for other plugins to use

uefi: Add the PCR0 value as the device checksum for system firmware
...
We can't actually access the UEFI ROM from userspace, but the PCR0 is a hash
built from the ROM itself. We could use this value to ensure the firmware has
been written correctly, and that the PCR0 matches the expected value specified
in the metadata.

uefi: Do not add devices with invalid GUIDs
...
Note: We deliberately don't add the device without 'UPDATABLE' as there's
nothing the user can actually do to repair this themselves.

uefi: Rename all intermediary files and UEFI variables to prefix fwupd
...
fwupdate prefix is used by fwupdate and this will prevent clashes in case
its used instead.

dell: Register devices with the uefi plugin rather than using libfwup directly
...
The device registration allows us to create a 'virtual' device that can accept
capsule updates that is not found in the ESRT.

uefi: Access /sys/firmware/efi/efivars directly rather than using efivars
...
This allows us to redirect the functions for our self tests.
