Replace Fresco with Coil

Fresco is replaced with Coil everywhere to make it possible to set 'minSdkVersion'
to 23. But Coil is not used directly to avoid splintering the dependency
everywhere in the code. Coil is wrapped by extension functions for 'ImageView'.

Some shared functionality is moved from 'DisplayUtils' into the
'ImageViewExtensions'.

The exisiting initialization of Coil has also be changed. The usage of the self
initialized OKHttp client is removed. If this one is added the
caching of the http client is used by Coil additionally to memory and
disk cache.

Resolves: #2227, #2376
