feat: improve isDefEq for projections
...
When solving `a.i =?= b.i`, we first reduce `a` and `b` without using
delta reduction. If at least one become a structure, we reduce the
projection. Otherwise, we try to solve `a =?= b`, only reduce `a.i`
and `b.i` if it fails.

...
Note that it does not use `MetaEval` to execute the term of type
`CommandEval`. Thus, we can now use `#eval` to execute simple commands.

fix: make sure OfScientific Float instance is never unfolded during type class resolution
...
This commit fixes issue reported at
https://leanprover.zulipchat.com/#narrow/stream/270676-lean4/topic/deterministic.20timeout/near/287654818
Type class resolution was diverging when trying to synthesize
```lean
HSub (optParam Float 0.0) (optParam Float 1.0) ?m.472
```
and Lean was diverging while unfolding
```lean
instance : OfScientific Float where
ofScientific m s e :=
if s then
let s := 64 - m.log2 -- ensure we have 64 bits of mantissa left after division
let m := (m <<< (3 * e + s)) / 5^e
Float.ofBinaryScientific m (-4 * e - s)
else
Float.ofBinaryScientific (m * 5^e) e
```
was being unfolded.
Anothe potential solution for the problem above is to erase the
`optParam` annotations before performing type class resolution.
