Move JS-to-C binding signatures from sqlite3-api-prologue.js to sqlite3-api-glue.js to allow for use of the new/experimental sqlite3.wasm.xWrap() feature which automatically binds JS functions to WASM/C as needed, which simplifies creation of bindings which take C function pointers. Reimplement sqlite3_exec(), sqlite3_create_collation(), sqlite3_progress_handler() to use this new feature.
