feat: add HashMap.get*_filter* lemmas specialized for LawfulBEq (#8399) 
This PR adds variants of `HashMap.getElem?_filter` that assume
`LawfulBEq` and have a simpler right-hand-side. `simp` can already
achieve these, via rewriting with `getKey_eq` under the lambda. However
`grind` can not, and these lemmas help `grind` work with `HashMap`
goals. There are variants for all variants of `HashMap`,
`getElem?/getElem/getElem!/getD`, and for `filter` and `filterMap`.

Aspirational test cases for grind

These are not expected to work yet; we're collecting examples that we'd like to make work!
