Adds new lerp factors to the keyboard pad handler In order to simulate triggers and analog buttons.
See "Analog Button Lerp Factor" and "Trigger Lerp Factor" in the yml in InputConfigs/Keyboard/.
Values Range from 0-100 as before, where 100 is instant press and 0 is never.
Currently I'm not planning any GUI element for this.
* Prefer default initializer over std::memset 0 when possible and more readable.
* Use std::format in trophy files name obtaining.
* Use vm::ptr<>::operator bool() instead of comparing vm::ptr to vm::null or using addr().
* Add a few std::memset calls in hle where it matters (or in some places just to document an actual firmware memcpy call).
