KT-57468 Kotlin assignment plugin: operation name cannot be found

The problem results in broken import quick fix and import optimizer on
the IDE side [1].

`AssignResolutionAltererExtension` introduced a possibility to override
 resolution of assignment statements. The inconsistency though is
 that `KtSimpleNameReference.getResolvesByNames` doesn't return a name
 for the overridden `=`. Kotlin as a language doesn't support this [2].

This commit eliminates the drawback above:
1. It fixes the name `assign` the `=` can be resolved to [3].
   This eliminates the need to search for the name, bypassing the
   plugins.
2. `KtSimpleNameReference.getResolvesByNames` returns `assign` among
   other names in case it deals with binary `=` and assignment is
   resolved.
3. `KtCompilerPluginsProvider` was extended to check plugins' presence.
   K1 implementation added.
