wasm: enable WASM_BIGINT
JavaScripts's BigInt feature provides support for arbitrary-precision
integers. This makes it possible to represent 64-bit integers; the
standard JS Number type supports 32-bit integers only (or more
accurately 53-bit integers - see Number.MAX_SAFE_INTEGER).
Enable WASM_BIGINT which makes Emscripten map int64_t and uint64_t
to BigInt when interfacing with JavaScript code.
This removes one of the conditions which enables
wasm-emscripten-finalize.
Task-number: QTBUG-103352
