Subject: [PATCH] Support for PReLU with both one dim and multiple dims slope
 for fixing issue on gpufunctests  (#74)

* [GPU] Support for PReLU with multiple dims slope tensor for GPU (#11782)

* reshape a slope tensor of channel-wise prelu

* changed to follow prelu spec

* added unittests for prelu with multiple dims slope

* Update constant.cpp

Blanks are added.

* added comments about PReLU slope reshape policy

* added int8 prelu fusion tests

* Update PReLU slope reshape policy for 1-dims
