[IGNITE-4663] BinaryUtils.doReadObjectArray can not read array with platform-only element type

• Type: Bug

Description

BinaryUtils.doReadObjectArray performs unnecessary class lookup when deserialize = false. When array elements are of platform-only type (platformId != 0), the class can never be resolved.

• arrays of user-defined types are not supported for platforms
• performance is suboptimal in binary mode (in Java and platforms)

Stack trace for platforms problem:
