9399ce8346 feat(library/vm/vm_string): provide native implementation of type string in the VM 
closes #1175

The types `string_imp` and `string.iterator_imp` were supposed to be
marked private, but we cannot do it because we need to provide
`string_imp.mk`, `string_imp.cases_on`, `string.iterator_imp.mk` and
`string.iterator_imp.cases_on` in the VM since we use a different
internal representation. Note that marking them as private does not
work since users can still access `string_imp.cases_on` using
meta-programming.
So, we need better support for private declarations.

Missing feature, char literals do not support non ASCII values.
That is, in the current implementation, we cannot write 'α'.
This will be implemented in the future.

The VM native implementation does not behave correctly for huge
strings (i.e., strings with more than 4G characters).
The problem is that the current implementation relies on
```
size_t force_to_size_t(vm_obj const & o, size_t def)
```
We may also have overflow problems in the string.iterator implementation
code. This is not a big deal right now, since I doubt we will try
to process string with more than 2^32 characters.

@Kha the `core_lib` and tests seem to be working correctly, but
we need more tests.

f36fca875c feag(frontends/lean): explicit delimiters in declaration parameters 
Comment from parser.h

This commit makes sure that all declaration parameters must be surrounded with some kind of bracket. (e.g., '()', '{}', '[]').
The goal is to avoid counter-intuitive declarations such as:

              example p : false := trivial
              def main proof : false := trivial

which would be parsed as

              example (p : false) : _ := trivial

              def main (proof : false) : _ := trivial

where `_` in both cases is elaborated into `true`. This issue was raised by @gebner in the slack channel.

Remark: we still want implicit delimiters for lambda/pi expressions. That is, we want to write

               fun x : t, s
           or
               fun x, s

instead of

               fun (x : t), s
