[OTA] Move OTARequestorDriver to clusters directory

[carol-apple]

Problem

#15926 moved OTARequestorInterface into the cluster directory. OTARequestorDriver needs to reference the OTARequestorInterface so it is best that it is also moved to the clusters directory.

Change overview

• Move OTARequestorDriver and the generic impl into clusters directory
• Move the mbed impl of the OTARequestorDriver into examples directory

Testing

Tree compiles
