feat(gnovm/pkg/gnolang): add compile time guards to fail on 32-bit architectures (#3643)

This change adds build constraints so as to panic if built for 32-bit
architectures as it is a project wide decision not to support them.

This allows the mainnet launch without sweating trying to make a bunch
of runtime changes for the gnovm.

Updates #3288
