feat: add archinfo metadata generation and integration

Browse Source 
- Introduced scripts and makefile targets for generating architecture information metadata.
- Updated the filelist generation to include archinfo metadata files.
- Modified software.mk to include archinfo source files and headers.
- Enhanced the ip_apb_wrapper and user_ip_wrapper to integrate archinfo components.
- Updated tests to ensure stability and correct path expansions for generated files.
- Removed unnecessary files from the clusterip filelist.

`bringup` retains the full automatic application-information report for

ARCHINFO ABI V2 exposes immutable build, configuration, topology, feature, and
technology identity. Its register specification, driver, standalone tests, and
formal properties are delivered by the
[archinfo IP repository](https://github.com/retroSoC/archinfo). The integration
generates matching RTL and C metadata headers from the source revision,
dependency lock, and canonical configuration digest.
Normal builds clear the release flag; an audited release flow sets
`BUILD_RELEASE=YES`, which is part of the canonical configuration digest.
OpenSTA runs a reproducible core-STA baseline for every CI PDK: IHP130 uses
`slow_1p08V_125C`, GF180 uses `ss_125C_4v50`, ICS55 uses the H7CR
`ss_1p08_125C` view, and SKY130 uses `ss_100C_1v40`.
