Bootspec has a mechanism called synthesis where you can synthesize
bootspecs if they are not present based on the generation link only.
This is useful for "vanilla bootspec" which does not contain any
extensions, as this is what we do right now.
If we need extensions, we can also implement our synthesis mechanism on
the top of it.
Enabling synthesis gives us the superpower to support non-bootspec
users. :-)
This commit adds settings key for configuring systemd-boot to the lanzaboot
nixos module. The are couple of the default values that are set from the usual
nixos boot.loader.systemd-boot options, they are merged with the user defined
configuration.
This commit modifies default loader.conf to boot into the latest nixos
generation by default, for when you have other operating systems installed.
Primary reason behind this PR is to allow extensible loader configuration.

The way the test was implemented previously did not make it fail if no
secret was appended to the initrd. Now it is implemented similary to the
initrd-secrets test in Nixpkgs and works correctly.
To minimize the number of arguments passed to `lzbt`, the loader config
is assembled outside `lzbt` and passed as a single argument.
Instead of reimplementing `consoleMode` under the `lanzaboote`
namespace, `config.loader.systemd-boot.consoleMode` is reused as is.
The test attributes and names are simplified and standardized. They now
roughly follow the same structure as the systemd-boot test in Nixpkgs.
Some comments are added and variable names changed to make it more clear
what they actually do.
