Add C++ query builder

[JasonAtClockwork]

Description of Changes

• Added a query builder for C++ module bindings
  • Added query-builder table/filter/join types
  • Added semijoin support with compile-time checks for lookup-table and indexed-field usage
  • Added support for returning query-builder queries from C++ views
  • Hooked query-builder metadata into the C++ table/view macros and V10 module-def path
• Added test coverage for the new C++ query-builder behavior
  • Compile tests for pass/fail cases
  • SQL tests for generated query output
  • Added a C++ test module for view primary key coverage

API and ABI breaking changes

• No intended API or ABI breaking changes
• Adds a new public query-builder API to the C++ bindings
• C++ views can now return query-builder query types in addition to materialized row results

Expected complexity level and risk

3 - Mostly contained to C++ bindings, but it touches macros, view registration/serialization, and module-def generation, so there are a few places where the pieces need to stay in sync.

Testing

• Run the C++ query-builder SQL tests [crates/bindings-cpp/tests/query-builder-compile/run_query_builder_compile_tests.sh]
• Smoke test a generated C++ module using query-builder views
