Since shim is inherently updated by shipping a new shim, the
latest built in revocations can include the most recent shim
revocations. Since CVE-2023-40547 is high impact, this revocation
should be available to everyone as soon as possible.
GRUB2 CVE-2023-4692 and CVE-2023-4693 are in the ntfs module that
only some vendors ship. Since some vendors did not ship an updated
GRUB2 for these issues, the revocation for these CVEs is not
included in the payload at this time.

Though we don't need to bump SBAT_LEVEL for this, we've decided to
change the level to 3 here in case
53509eaf2253e23bfb552e9386fd0877abe592b4 turns out to be worse than we
think it is, so we can fix that easily later.

Two places we missed still have 0 for an sbat version - one doc and one
in our data csv.
This fixes those.

The Secure Boot Advanced Targeting (SBAT) [0] is a Generation Number Based
Revocation mechanism that is meant to replace the DBX revocation file list.
Binaries must contain a .sbat data section that has a set entries, each of
them consisting of UTF-8 strings as comma separated values. Allow to embed
this information into the fwupd EFI binary at build time.
The SBAT metadata must contain at least two entries. One that defines the
SBAT version used and another one that defines the component generation.
This patch adds a sbat.csv that contains these two entries and downstream
users can override if additional entries are needed due changes that make
them diverge from upstream code and potentially add other vulnerabilities.
The same SBAT metadata is added to the fallback and MOK manager binaries
because these are built from the same shim source. These need to have SBAT
metadata as well to be booted if a .sbat section is mandatory.
