logictest: remove local-mixed-25.3 test configuration

Part of the quarterly M.4 "Bump MinSupported" task as outlined in
`pkg/clusterversion/README.md`.

After bumping MinSupported from v25.3 to v25.4, the local-mixed-25.3
test configuration is no longer needed since it simulates a mixed-version
cluster with v25.3 nodes, which can no longer connect to the cluster.

This commit:
- Removes the local-mixed-25.3 config from logictestbase.go
- Removes it from the default-configs and schema-locked-disabled sets
- Deletes the generated test directories for local-mixed-25.3
- Removes all references from logic test files (skipif/onlyif directives)
- Removes empty LogicTest directive lines that resulted from deletions
- Regenerates Bazel BUILD files via `./dev gen bazel`

Note: pebbleFormatVersionMap updates are deferred to a separate PR.
Following the pattern from PR #157767 (v25.2→v25.3 bump), pebble.go is
not modified in the M.4 PR. The map will be updated separately once
V26_1_* internal versions with Pebble format changes are added, similar
to how V25_4_PebbleFormatV2BlobFiles was added before the previous M.4.

Changes affect 64 test files that had skipif or onlyif directives
referencing local-mixed-25.3, plus the generated test files and BUILD
files that were auto-generated based on the removed configuration.

Part of #157767 (reference PR for this quarterly task pattern).

Release note: None
