all: tidy up deprecation warnings a bit
In APIs like Runtime.Compile, point to non-deprecated alternatives,
rather than pointing to methods which are themselves also deprecated.
While here, tidy up other deprecated notes so that they use doc links.
Also note that Instance.LookupField had two deprecation notices;
only the second seems to have been up to date.
Fixes #1735.
