[CPU] Fix resolve edge conflicts Convert insertion

[EgorDuplensky]

Details

• Current version does not clean extra edge in case Convert + Reorder is inserted. In this case we need to remove an edge, which is replaced with Convert node first, and then remove childEdge of the newly inserted Convert node, after Reorder is inserted.
• The idea is to simplify this logic and do one thing at a time:

1. Insert Convert.
2. If Reorder is still necessary for the new inserted edge, it will be handled later in the loop.

It seems to be impossible to write a test for x86 platform, since there is no reorder which does not support precision conversion.

What was the precision/layout configuration caused issue on ARM?
Still think it worth to implement subgraph test even if it will be benefitial only for non x86 systems.
