Expand "sqlite3_vfs*" JS-to-WASM function argument conversions to accept VFS names (JS strings) and capi.sqlite3_vfs instances. Implement sqlite3_js_vfs_create_file() to facilitate creation of file-upload features which store the file in VFS-specific storage (where possible, e.g. "unix" and "opfs" VFSes). Correct an argument type check in the SQLite3Error and WasmAllocError constructors.
