Pull request overview

This PR aims to prevent generating ELF files that require extended section numbering by enforcing an upper bound on the number of emitted ELF sections (and a derived upper bound on “pages” for AIE2PS ctrlcode generation).

Changes:

• Added a hard cap on the number of ELF sections created by elf_writer via a new add_section_by_name() helper.
• Added a derived “max pages” limit in aie2ps_preprocessor and tracked total pages across columns.
• Switched page index tracking to uint32_t in the AIE2PS preprocessor loop.
