  [mlir][acc] Fixed side effects for [first]private/reduction. (#180791)

This patch moves the definitions of memory effects for the data
entry/exit operations into C++ code. The main reason for this
is to modify the effects of [first]private and reduction
operations: they should not access `CurrentDeviceIdResource`
when they are located inside a compute construct.

The ODS to C++ migration was done with AI assistance. I reviewed
these changes and made sure it was an NFC change. After that
I modified [first]private and reduction implementations.
