ac0352b584 refactor(kernel): remove quotitent normalizer extension 
The `quot` type is now implemented in the kernel.
We will do the same thing for inductives.
We will not support normalizer extensions anymore in Lean4.
It doesn't make sense since we settled with 2 extensions: quotients and
inductives. Moreover, any new extension would require substantial
changes (e.g., code generator).
The normalizer_extension feature was useful when we were experimenting
with different kernel flavors.

0556412f8d refactor(*): add runtime folder 
@kha The runtime folder includes what is needed to link a
standalone Lean program. It is still contains some unnecessary files.
We will be able to remove them after we release Lean4.

d0d75c0923 refactor(kernel): reduce number of configurations supported in the kernel 
Now, eta and impredicativity are assumed to be always true.

Motivation: the rest of the system assumes eta.
Regarding impredicativity, we decided to support only the standard library.

1b4c9f63ce perf(kernel/environment): improve is_descendant performance, optimize for the common case: the is_descendant tree is huge but has few deep branches 
This is an important optimization for module.cpp. The benchmark tests/lua/slow/mod2.lua is a good example where the cost of is_descendant was neutralizing the benefit of the replace method.

94fa987814 fix(kernel/type_checker): is_proposition method was still assuming that a Pi never has type Bool 
The method is_proposition was using an optimization that became incorrect after  we identified Pi and forall.
It was assuming that any Pi expression is not a proposition.
This is not true anymore. Now, (Pi x : A, B) is a proposition if B is a proposition.
