### Description
- Updates the C++ API function `Ort::KernelContext::GetAllocator` to
return a `Ort::Allocator`, which releases the allocator instance on
destruction.
- Fixes a memory leak in a unit test by using the fixed
`Ort::KernelContext::GetAllocator` API.



### Motivation and Context
Users of the C++ API should not have to manually call `ReleaseAllocator`
on the result of `Ort::KernelContext::GetAllocator`. This expectation
will make leaking memory common.
