added error code and removed all error messages (Azure#12967)

* added error code and removed all error messages as discussed

* added error description back

* updated IncompatibleVMSize descirption and UnsupportedVMSize. Removed VMSizeNotSupportedByDesciption as it is not a PoolResizeErrorCode returned as Code (returned as Details.Code instead)

* fix casing for AllocationTimeout
