chore: turn some crashes into errors (#8402) 
This PR prevents some nonsensical code from crashing the server.

Specifically, the kernel is changed to
- properly check that passed expressions do not contain loose bvars,
which could lead to a segmentation fault on a well-crafted input
(discovered through fuzzing), and
- check that constants generated when creating a new inductive type do
not overwrite each other, which could lead to the kernel taking
something out of the environment and then casting it to something it
isn't.

Partially addresses #8258, but let's keep that one open until the error
message is a little better.

Fixes #10492.
