JIT shouldn't always be enabled

This would always enable the jit feature. I do know Cranelift has an interpreter backend, but having the JIT always enabled pollutes the build by adding 100 more satellite dependencies to always build with. Try not to include JIT in the workspace, but rather add a jit feature in rapace crate, and add jit to the default of rapace, so that people like me who don't have good JIT support, for example, I'm running it in a RISC-V microcontroller with RV32IMAC which Cranelift clearly doesn't supports and has to come up with a special communicate channel via UART or I2C.
