fix: Update wit-bindgen compatibility list to include 0.47.0, 0.48.x, and 0.49.0

The embedded runtime in rust_wasm_component_bindgen.bzl was hardcoded to only
accept wit-bindgen CLI versions 0.44.0-0.46.0. This broke after upgrading to
wit-bindgen 0.49.0. The embedded runtime API (Cleanup, CleanupGuard,
run_ctors_once, maybe_link_cabi_realloc) remained compatible throughout these
versions, so we can safely add them to the compatible versions list.

Fixes CI test failures in smoke tests and compatibility tests.
