EarlGrey 2 fails to compile in Xcode 16.3

When trying to build a project using EarlGrey 2.2.2 in Xcode 16.3, I now get the error:

```
Cast from 'id Nullable ()(id Nullable strong, Ivar **Nonnull)' (aka 'id **Nullable ()(**strong id Nullable, struct objcivar * Nonnull)') to 'UITouchFlagsGetVariableFunction' (aka 'UITouchFlags ()(*_strong id, struct objc_ivar *)') converts to incompatible function type
```

on line 443 in `SetTouchFlagPropertyInUITouch` in the file `GREYTouchInjector.m`

The `UITouchFlagsSetVariableFunction` line (450) also causes the same sort of problem:

```
Cast from 'void (*)(id _Nullable __strong, Ivar _Nonnull, id _Nullable __strong)' (aka 'void (*)(__strong id _Nullable, struct objc_ivar * _Nonnull, __strong id _Nullable)') to 'UITouchSetVariableFunction' (aka 'void (*)(__strong id, struct objc_ivar *, UITouchFlags)') converts to incompatible function type
```

This is preventing me from being able to update the project to use Xcode 16.3.

Is there a safe workaround I can use for this? Thanks!

Reproduce the EarlGrey 2.2.2 build with Xcode 16.3 and inspect GREYTouchInjector.m at lines 443 and 450, where the UITouch function-pointer casts fail. Check the surrounding function-pointer definitions and compiler diagnostics; done means the project compiles successfully under Xcode 16.3 without breaking touch injection.
