b1774222 - [flang] Emit `fir.global` in the global address space (#146653)

[flang] Emit `fir.global` in the global address space (#146653) Instead of emitting globals in the program/default address space, emit them in the global address space. This also requires changes how address of code-gen is handled, we need to cast to the default address space to prevent code-gen issues.
