SGX target: simplify usercall internals

This moves logic from assembly to Rust and removes the special
case for exit/panic handling, merging it with regular usercall
handling.

Also, this fixes a bug in the exit usercall introduced in a75ae00.
The bug would make regular exits look like panics with high
probability. It would also with some probability leak information
through uncleared registers.
