[PATCH v3 7/7] scripts/sbom: remove the command-specific parsers

[Luis Augenstein <luis.augenstein@tngtech.com>]

With the build inputs taken from make_prereqs_ and deps_, the
command-specific parsers are no longer needed. Remove them, and with
them the --do-not-fail-on-unknown-build-command option, which only
existed to tolerate build commands that the parsers did not support.

-Unknown Build Commands
-~~~~~~~~~~~~~~~~~~~~~~
-
-Because the kernel supports a wide range of configurations and versions,
-KernelSbom may encounter build commands in ``.cmd`` files that it does
-not yet support. By default, KernelSbom will fail if an unknown build
-command is encountered.
-
-If you still wish to generate SPDX documents despite unsupported
-commands, you can use the ``--do-not-fail-on-unknown-build-command``
-option. KernelSbom will continue and produce the documents, although
-the resulting SBOM will be incomplete.
-
-This option should only be used when the missing portion of the
-dependency graph is small and an incomplete SBOM is acceptable for
-your use case.
