Avoid copying measurements when updating last cache

Description

Avoid copying measurements on last cache write path

This PR avoids materializing a copied raw measurement array when InsertRow/InsertTablet nodes update last cache. Write nodes pass their existing measurements array to cache update APIs, and cache update resolves raw measurement names from measurement schemas by index.

Preserve alias and failed-column semantics

TableDeviceLastCache and tree schema cache now resolve schema raw names only when the original measurement slot is still valid, so failed measurements remain skipped. getRawMeasurements() keeps copy-on-write behavior for callers that still need a raw measurement array.

Tests

• Added alias regression coverage for tree last cache update.
• Added coverage for copy-on-write getRawMeasurements() behavior.

Validation:

• mvn -Ddevelocity.off=true -DspotlessFiles=... -pl iotdb-core/datanode spotless:apply
• git diff --check

mvn ... test-compile was attempted but the local workspace fails on existing generated Freemarker sources (IFill, Accumulator, ComparatorChain resolution), unrelated to this change.
