34dc2572f3 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.

c2166fc602 chore: work around parameterized parser syntax kinds 
We should find a better solution for calling parameterized parsers such
as `matchAlt` than these helper definitions that confuse the antiquotations.

d499e67c87 fix: incorrect antiquotation kind annotations 
Apparently, none of them led to incorrect syntax trees, but `TSyntax`
still disapproves.

6c64b1b20b chore: work around for type inference 
It seems type information often flows from the body to the loop
variable, which is problematic with coercions.

5e334b3e90 chore: postpone TSyntax adoption for some parts 
The namespace `TSyntax.Compat` can be opened for a coercion
`Syntax -> TSyntax k` for any `k`, as otherwise this PR would never be done.

a78302243c refactor: strengthen Syntax signatures 
Most notable change: `Quote` is now parameterized by the target kind.
Which means that `Name` etc. could actually have different
implementations for quoting into `term` and `level`, if that need ever
arises.
