Pull request overview

This PR updates the PXB automated backup regression scripts to automatically enable --check-tables during xtrabackup --prepare when running on Percona XtraBackup versions that support it (>= 8.4.0-6), improving validation coverage during backup/restore testing.

Changes:

• Add XtraBackup version parsing/normalization that includes the -<release> component (e.g., 8.4.0-6).
• Introduce a helper to build --prepare argument lists and automatically append --check-tables for supported PXB versions.
• Minor deduplication by setting restore_params = prepare_params in several component-encryption flows.

File	Description
test_scripts/pxb/upgrade_backup_tests.py	Uses the new helper prepare-args builder so upgrade prepare steps can auto-add --check-tables when supported.
test_scripts/pxb/test_helper.py	Adds PXB version normalization including release, introduces version-gated prepare arg augmentation (--check-tables), and removes some duplicated param construction.

Can you just write a description about why does one version normalization function not work for both PS and PXB considering that PS versions look like 8.4.10-10 and PXB 8.4.0-6, so they both have the last digit after dash character.
