[Bug 2064023] [NEW] Installer should detect small ESP in a dual boot

[Mario Limonciello]

Public bug reported:

If someone sets up Windows before Ubuntu, Windows will create an EFI
system partition that gets reused by Ubuntu.

This is generally fine, but a major problem is that the EFI system
partition is also where firmware updates are staged during a BIOS
update.

If the ESP is too small, then the update won't be able to run.  The
command line fwupdmgr tool will show this type of message:

/boot/efi does not have sufficient space, required 93.2 MB, got 66.8 MB

This is a situation that should be handled at install time.  If the ESP
is too small to support updates later it should be resized or a new one
created for Ubuntu to use.
