Add linux-initrd-chain to the chainload action and initrd-chain to the
edera action. Each file in the list is read in order and concatenated
into a single initrd. The chain can't be combined with the single
initrd option on the same action.
BLS entries with multiple initrds, either as repeated initrd lines or
as multiple paths on one line, previously only loaded the last one.
Parse all of them and set them in the initrd-0 through initrd-7 slots,
which the autoconfigured BLS action now chains. Unused slots stamp to
the filesystem root and are skipped. Entries with more than 8 initrds
are skipped with a warning.
A single BLS entry that could not be read, was not valid UTF-8, or
failed to parse aborted entry generation and therefore the whole boot,
contrary to the generator's documented best-effort behavior. Log a
warning and skip the entry instead.
Autoconfigure detects BLS when either \loader\loader.conf or
\loader\entries exists, but the BLS generator required the entries
directory and failed the boot without it. This broke ESPs that only
have a loader.conf, such as UKI-only systemd-boot setups. Generate no
entries when the directory is missing.
