feat: have "formulation" as part of the BOM - MBOM

[jkowalleck]

Is your feature request related to a problem? Please describe.

CycloneDX 1.5 supports formulation: https://cyclonedx.org/guides/sbom/formulation
This could be used to document how webpack was configured and how it compiled/packed the results.

Describe the solution you'd like

• if target is spec 1.5, then the result should contain information how webpack built the result.
  • the details are to be discussed here: [FEATURE IDEA] MBOM and formulation #1346
• add Manufacturing Bill of Materials (MBOM) to the capabilities/keywords
• ... to be continued & discussed

Describe alternatives you've considered

Additional context

need to POC/investigate what information can be gathered from webpack, and if the information qualifies for "CDX formulation"
