  [flang][cuda] Compute offset on cuf.shared_memory ops (#131395)

Add a pass to compute the size of the shared memory (static shared
memory) and the offsets of each variables to be placed in shared memory.
The global representing the shared memory is also created during this
pass.

In case of dynamic shared memory, the global as a type of
`!fir.array<0xi8>` and the size of the memory is set at kernel launch.
