  [flang][cuda] Detect illegal data transfer in semantic (#125591)

When the LHS is a device variable and the RHS has implicit transfer,
this is considered as an illegal transfer according to
https://docs.nvidia.com/hpc-sdk/compilers/cuda-fortran-prog-guide/index.html#implicit-data-transfer-in-expressions.

Detect this is semantic .
