Refactor buffer ReadWrite and Copy tests (#2259)

Browse Source 
This change refactors the following tests to use RAII to clean-up
allocated resources on exit, and adds additional changes as mentioned
below:

- test_arrayreadwrite
    - Allow different `cl_mem_flags` to be passed to the test.
- test_bufferreadwriterect:
    - Allow different `cl_mem_flags` to be passed to the test.
    - Customisable copy, read and write functions.
- test_buffer_copy
- Fill the destination buffer with `invalid_ptr` instead of `out_ptr` if
created with `CL_MEM_(USE/COPY)_HOST_PTR`.
- test_buffer_partial_copy
- Fill the destination buffer with `invalid_ptr` instead of `out_ptr` if
created with `CL_MEM_(USE/COPY)_HOST_PTR`.
