Cannot use ext::ai::search from the query builder

[scotttrinh]

Code

e.ext.ai.search(e.SomeIndexedType, new Float32Array([0.0]));
// or with params, which type checks but does not work at query-build-time
e.params({ searchTerm: e.array(e.float32) }, (params) => e.ext.ai.search(
  e.SomeIndexedType,
  params.searchTerm
));

Error or desired behavior

No function overload found for 'e.ext.ai.search()' with args: Element: default::Post (Many), Element: arraystd::float32 (One)

Digging in here, it seems that in our functionality that compares the argument type to the function type definition, we end up casting the std::float32 to std::number and then comparing against std::float32 (which is false), and we are not generating an implicit cast map entry between std::float32 and std::number so that comparison is also returning false.
