  [CIR] Cast alloca for function parameter to the right address space (#220836)

Function parameters are stored into temporary allocas and for
address-space aware targets allocas may yield pointers to address spaces
that are different from default address space or the address space of
the parameter type. Do a cast to avoid mismatch. The address space
mismatch was reproduced using cir.ternary op returning a function
parameter and a local variable. For local variables and return
temporaries we already cast alloca address space to temporary address
space but not for function parameter allocas.
