Do not export the numerous Emscripten HEAPxy symbols and remove the last remaining JS code which references them. They have long-since been replaced by internal equivalents and a specific feature check on one of them (which is also no longer needed) is triggering an exception from Emscripten. More details are in [ https://github.com/emscripten-core/emscripten/issues/24656 | Emscripten ticket #24656 ], noting that this is not an Emscripten bug but an Emscripten behavior change brought it to light.

Experimentally add sqlite3.oo1.DB/Stmt.wrapHandle(), which allow DB/Stmt instances to wrap a (sqlite3*)/(sqlite3_stmt*) optionally with or without taking ownership of it. The intent is to enable mix-and-match use of the C API, the oo1 API, and any other hypothetical API which exposes those pointers. oo1.Stmt.parameterCount is now a property access interceptor like Stmt.columnCount is, but that doesn't change how it's used.
