  [CIR] Function calls with aggregate arguments and return values (#143377)

This patch updates cir.call operation and allows function calls with
aggregate arguments and return values.

It seems that C++ class support is still at a minimum now. I tried to
make a call to a C++ function with an argument of aggregate type but it
failed because the initialization of C++ class / struct is NYI. I also
tried to inline this part of support into this patch, but the mixed
patch quickly blows in size and becomes unsuitable for review. Thus,
tests for calling functions with aggregate arguments are added only for
C for now.
