fix: add base addr to symbol offset

[not-matthias]

Changes in this PR:

• Merge the load bias and base address calculation of unwind_info and perf_map
  • (we previously had 2 separate implementations - it's now easier to verify and maintain)
• Add the load bias to the symbol offset
• Add test to for the_algorithms to ensure we get the right addresses

Pull Request Overview

This PR fixes symbol address calculation by adding the base address to symbol offsets instead of the load bias, and consolidates the address calculation logic between unwind_info and perf_map.

• Merged load bias and base address calculation into a shared elf_helper module
• Changed symbol offset calculation to use base address rather than load bias for better accuracy
• Added test coverage for the_algorithms binary to verify correct address calculations
