Mirror the backtrace improvements from PR #577 (Rust/TS) to the C# and
C++ module bindings so that stack traces captured by the host show
actual reducer/procedure/view function names instead of anonymous
wrappers.

C# changes:
- Add [MethodImpl(NoInlining)] to all generated Invoke() methods in
  reducer, procedure, and view dispatcher classes. This prevents the
  JIT/AOT from inlining these frames away, ensuring they appear as
  named WASM functions in wasmtime-captured backtraces.
- Add Log.Error() in the reducer error handler for consistency with
  procedures and views, which already log full exceptions.

C++ changes:
- Add __attribute__((noinline)) to user function definitions in all
  macro variants: SPACETIMEDB_REDUCER, SPACETIMEDB_REDUCER_NAMED,
  SPACETIMEDB_INIT, SPACETIMEDB_CLIENT_CONNECTED,
  SPACETIMEDB_CLIENT_DISCONNECTED, SPACETIMEDB_VIEW,
  SPACETIMEDB_VIEW_NAMED, SPACETIMEDB_PROCEDURE, and
  SPACETIMEDB_PROCEDURE_NAMED. This ensures the actual user function
  name appears as a distinct frame in WASM backtraces rather than
  being optimized into the surrounding lambda wrappers.
