Improve metadata OOM diagnostics

[Caideyipi]

Description

Backport #18039 / 9dd1bb8 to dev/1.3.

Metadata OOM diagnostics

• Track matched, expanded, and generated result columns during query analysis.
• Track schema-fetch deserialized column counts and schema tree memory reservation.
• Enrich MemoryNotEnoughException with column counts, SLIMIT/SOFFSET, ALIGN BY DEVICE guidance, and memory details.
• Add unit coverage for the enriched diagnostics.

Branch adaptation

dev/1.3 does not have the newer query i18n source roots, so the diagnostic message templates are kept as local constants in MPPQueryContext for this branch.

Verification

• mvn spotless:apply -pl iotdb-core/datanode
• mvn "-Ddevelocity.off=true" -pl iotdb-core/datanode -Dtest=MPPQueryContextTest test fails during datanode compilation before running the test, with unrelated compile errors around PipePeriodicalLogReducer and FileUtils#createLink.
