feat(core): add experimental _queryProps for Arrow aggregate-derived layer values - #11101

Summary

Stacked on #11100. Introduces the experimental layer prop _queryProps, mapping existing numeric layer props to SQL-style aggregate expressions evaluated against an Apache Arrow table.

new ScatterplotLayer({
  data: arrowTable,
  _queryProps: {radiusScale: '100 / MAX(population)'},
  transitions: {radiusScale: 500}
});

• Evaluates MIN / MAX / AVG / SUM / COUNT through math.gl's Arrow aggregate compiler, plus arithmetic via the portable expression evaluator.
• Calls the protected setDerivedProps() from feat(core): support internal derived layer prop overrides #11100 with resolved numeric values, allowing ordinary prop diffing and uniform transitions.
• Lazy-loads expression evaluation; preserves declarative props, ignores stale async query completions, and clears overrides when _queryProps is removed.
• Numeric prop targets only; Arrow Table inputs only. No new changes to ComponentState or general SQL query execution.
• Includes evaluator tests and API documentation.

Validation: Draft; builds/tests have not been executed here. Initial implementation rescans on input/query changes and does not yet maintain progressive accumulator state.

Dependency: #11100 must merge first or be rebased into this branch.
