feat: add FeGaussianBlur filter (#2352)

# Summary

Continuation of #2316 
Introducing new filter `FeGaussianBlur`.

### Implementation notes

On Android there is no easy way to fully implement Gaussian blur, as
there is no native api for this. While a basic implementation is
possible with `RenderScript`, it does not allow for blur in one axis and
greater than `25`

## Test Plan

Example app -> Filters -> FeGaussianBlur

## Compatibility
