PY-85638 PY-85893 Use soft-key soft-value map for TypeEvalContext caches

Browse Source 
This prevents the caches from blowing up in size when analyzing a lot of files in a row

The most obvious example is running `Analyze code` on the whole project. Previously, all PSI elements from all files would pollute the cache, potentially consuming multiple Gb of memory. See PyDjangoSourcesPerformanceTest as an example. It used to require 16 Gb of heap, and it would still sometimes fail with OOM. Now, it runs smoothly with 2Gb of heap
