Improve shadow rendering with non-default camera FOV (#11385)
* Adjust minimum filter radius for perspective
* Expand shadow frustum when camera FOV changes, reuse FOV distance adjustment from numeric.cpp
* Read shadow_soft_radius setting as float
* Use adaptive filter radius to accomodate for PSM distortion
* Adjust filter radius for texture resolution
