feat: reduce calls to patchelf

[mayeut]

patchelf is called multiple times to update soname, remove/replace needed, update RPATH.

This can be done in a single command line call allowing for faster patching and reducing the chance of running into a patchelf issue with multiple updates to a single ELF file.

Pull request overview

This PR refactors ELF patching so multiple modifications (SONAME, DT_NEEDED changes, RPATH updates) can be applied with fewer patchelf invocations, reducing repair time and minimizing repeated writes to the same ELF.

Changes:

• Introduces ElfPatcher state tracking (ElfUpdateInfo) and a batched Patchelf.apply_updates() implementation.
• Updates wheel repair flow to queue edits and apply them once at the end, including handling script-to-shim moves via update_elf_path.
• Adjusts unit tests to validate queued-update behavior instead of asserting multiple subprocess calls.

File	Description
tests/unit/test_repair.py	Reworks RPATH-append tests to validate queued state in ElfPatcher rather than mocking subprocess calls.
tests/unit/test_elfpatcher.py	Adds overlap-validation tests for queued DT_NEEDED changes; updates Patchelf invocation expectations to match batching.
src/auditwheel/repair.py	Queues patch operations during repair and applies them once; updates update tracking when ELF scripts are moved.
src/auditwheel/patcher.py	Adds queued-update infrastructure and implements batched patchelf execution via apply_updates().

This PR comes from the investigation regarding the use lief-patchelf in #664
There are also bugs in LIEF which are triggered when iteratively patching the same ELF file (not yet reported upstream).
