CI: {caching,test,bench}: mk cache aware of package dep versions #2532

1. CI caches 3rd patry dependency binaries. 2. That is why we do not want to trigger on all `.cabal` changes. We want to cache only when changes in `.cabal` descriptions lead to changes in versions of deps used, or in their compilation flags. `freeze` files: For example the bits of the resulting `.freeze` file: active-repositories: hackage.haskell.org:merge constraints: any.Boolean ==0.2.4, ... any.HsYAML ==0.2.1.0, HsYAML -exe, any.HsYAML-aeson ==0.2.0.1, HsYAML-aeson -exe, any.JuicyPixels ==3.3.6, JuicyPixels -mmap, any.MemoTrie ==0.6.10, MemoTrie -examples, ... any.QuickCheck ==2.14.2, QuickCheck -old-random +templatehaskell, aeson -bytestring-builder -cffi -developer -fast, ... any.aeson-pretty ==0.8.9, aeson-pretty -lib-only, bifunctors +semigroups +tagged, any.blaze-textual ==0.2.2.1, blaze-textual -developer -integer-simple +native, ... any.brittany ==0.13.1.2, brittany -brittany-dev-lib -brittany-test-perf, ... any.clock ==0.8.2, clock -llvm, any.cmdargs ==0.10.21, cmdargs +quotation -testprog, ... any.comonad ==5.0.8, comonad +containers +distributive +indexed-traversable, ... any.hashtables ==1.2.4.2, hashtables -bounds-checking -debug -detailed-profiling -portable -sse42 +unsafe-tricks, haskell-language-server -alternatenumberformat +brittany +callhierarchy +class +eval +floskell +fourmolu +haddockcomments +hlint -ignore-plugins-ghc-bounds +importlens +modulename +ormolu -pedantic +pragmas +qualifyimportednames +refineimports -rename +retrie +splice +stylishhaskell +tactic, ... any.hlint ==3.2.7, hlint -ghc-lib +gpl -hsyaml +threaded, hls-eval-plugin -pedantic, hls-graph -embed-files -pedantic -stm-stats, hls-hlint-plugin -ghc-lib -hlint33 -pedantic, ... any.integer-logarithms ==1.0.3.1, integer-logarithms -check-bounds +integer-gmp, ... any.lens ==5.0.1, lens -benchmark-uniplate -dump-splices +inlining -j +test-hunit +test-properties +test-templates +trustworthy, ... any.scientific ==0.3.7.0, scientific -bytestring-builder -integer-simple, any.semigroupoids ==5.3.6, semigroupoids +comonad +containers +contravariant +distributive +tagged +unordered-containers, any.semigroups ==0.19.2, semigroups +binary +bytestring -bytestring-builder +containers +deepseq +hashable +tagged +template-haskell +text +transformers +unordered-containers, ... any.transformers-compat ==0.6.6, transformers-compat -five +five-three -four +generic-deriving +mtl -three -two, ... any.vector ==0.12.3.1, vector +boundschecks -internalchecks -unsafechecks -wall, any.vector-algorithms ==0.8.0.4, vector-algorithms +bench +boundschecks -internalchecks -llvm +properties -unsafechecks, ... index-state: hackage.haskell.org 2021-11-29T12:28:17Z ``` You got the idea. `freeze` collects stuff for dependencies. I also checked - it solves & collects all package configuration across all subprojects in one file.

Before we not had this at all. Now - most cases would use it. But for example, all HLS subprojects can not solve single version of deps for GHC 9.0 at once. And depending on `.cabal` is not the right way, as it means to account of only 1 configuration of many in the project.
