wasmtime: Allow Wasmtime to handle SIGFPE (#9945) 

Recently Wasmtime switched code generator tactics for the implementation
of integer division. This means that Wasmtime expects to receive SIGFPE
for divide-by-zero traps and similar. This is similar to other signals
that Wasmtime is expected to handle in JIT code.

This commit adds an option for Wasmtime to let it handle signals in the
same manner that it's allowed to handle SIGILL and SIGSEGV currently.
