DITConfiguration: Prevent a crash if images fail to load

2025-11-29T22:54:48+00:00

Recently came across a strange issue where Dolphin would hard crash in most games with this error:

```sh
/usr/include/c++/15.2.1/optional:1165: constexpr const _Tp* std::optional<_Tp>::operator->() const [with _Tp = InputCommon::ImagePixelData]: Assertion 'this->_M_is_engaged()' failed.
```

The culprit turned out to be accessing `host_key_image` which is an `std::optional` thay may return `std::nullopt`. I'm not sure why this issue started occuring for me since I've had no issue with my Dynamic Input Textures in the past? But this fixes a crash if the image fails to load.

Common and VideoCommon: Change texture data from std::vector to Common::UniqueBuffer.

InputCommon: Introducing the "Dynamic Input Texture". Configuration links an emulated input action to an image based on what host key is defined for that emulated input. Specific regions are called out in configuration that mark where to replace an input button with a host key image.
