If an OpenCL driver returns `CL_PROGRAM_BINARY_TYPE_INTERMEDIATE`
(defined in the `cl_khr_spir` extension to enable SPIR 1.2 not SPIR-V)
when querying `CL_PROGRAM_BINARY_TYPE` we should handle this gracefully.
This patch maps the `CL_PROGRAM_BINARY_TYPE_INTERMEDIATE` to
`UR_PROGRAM_BINARY_TYPE_NONE`. From the users perspective these are
semantically equivalent as they both require compilation before the
program can be used to create a kernel.

Replace uses of `sizeof(const char*)` with `std::strlen(const char*)` in
CUDA adapter specific kernel tests.

These changes to the *Adapter Change Process* aim to bring the process
up to date with current practice by describing how the *ready to merge*
label is being used and also to move the undrafting of *intel/llvm* pull
requests earlier in the process to garner approvals from code-reviewers
sooner to alleviate a bottleneck in the merge pipeline.
