Motivation: make sure the behavior is consistent with other arithmetic
operators.
This commit also removes the instance
```
instance : HMod (Fin n) Nat (Fin n) where
hMod := Fin.modn
```
because we have a coercion from `Fin n` to `Nat`.
Thus, given `a : Fin n` and `b : Nat`, `a % b` is ambiguous.

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.
