clusterversion: bump MinSupported from V25_2 to V25_3

This change updates the minimum supported cluster version from 25.2 to 25.3,
removing all 25.2-specific code and infrastructure.

Changes include:
- Updated MinSupported constant from V25_2 to V25_3
- Renamed V25_3_* version keys with TODO_Delete_ prefix
- Updated Pebble MinimumSupportedFormatVersion
- Removed 25.2 bootstrap data files (4 files)
- Deleted release_25_2 schema changer rules (~30 files)
- Removed local-mixed-25.2 and cockroach-go-testserver-25.2 logictest configs
- Updated skipif directives in ~200+ test files
- Regenerated Bazel build files

Part of M.4 task (quarterly version bump process).

Release note (ops change): The minimum supported version for upgrades is now
25.3. Clusters running 25.2 or earlier must upgrade to 25.3 before upgrading
to this version.

Epic: None
