Improve shadow rendering with non-default camera FOV (#11385)

Browse Source 
* 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
