Subject: Fix PostOp dependency

In general src headers should not be included in any public header of
other modules.

Since there are modules (graph, tests) that rely on specific PostOp definitions
in the previous src/core/experimental/PostOp.h, export it to the public
arm_compute header

Resolves COMPMID-4974
