Implement savedcmd_parser module for extracting input files from kernel build commands.

Implement command graph generation by parsing .cmd files to build a dependency graph. Add CmdGraph, CmdGraphNode, and .cmd file parsing. Supports generating a flat list of used source files via the --generate-used-files cli argument.

Add hardcoded dependencies and .incbin directive parsing to discover dependencies not tracked by .cmd files.

Implement Python dataclasses to model the SPDX classes required within an SPDX document. The class and property names are consistent with the SPDX 3.0.1 specification.

Add infrastructure to serialize an SPDX graph as a JSON-LD document. NamespaceMaps in the SPDX document are converted to custom prefixes in the @context field of the JSON-LD output. The SBOM tool uses NamespaceMaps solely to shorten SPDX IDs, avoiding repetition of full namespace URIs by using short prefixes.

Implement the kernel_file module that collects file metadata, including license identifier for source files, SHA-256 hash, Git blob object ID, an estimation of the file type, and whether files belong to the source, build, or output SBOM.

Implement the SPDX output graph which contains the distributable build outputs and high level metadata about the build.

Implement the SPDX source graph which contains all source files involved during the build, along with the licensing information for each file.

Verify that SPDX-License-Identifier headers at the top of source files are parsed correctly.

createdcli argument for CreationInfo object. This does not need to be a cli argument. We can just use the latest modified timestamp of the provided root artifacts--write-output-on-errorcli argument to Makefile. This allows people to use the tool by default even if there are some commands that cannot be parsed. (This was for example a problem in https://birdcloud.org/bc/Linux_Kernel_Missing_SPDX_ID_lines_from_build_SBOMs)originatedByproperty from Package Elements. This was currently set to the KernelSbom agent who created the SBOM. This is likely a wrong usage of the property. If using the property in the future again it should be referencing the Agent who created the Package files.
