- [x] Add `CL_DEVICE_NAME` to list of device properties printed into the
clDeviceInfo file for offline compilation testing.
- [x] Add `get_device_name` helper function.
- [x] Update offline compiler interface explanation file with
`CL_DEVICE_NAME` and `CL_DEVICE_IMAGE_SUPPORT` which was missed from
this file when added.
* Use std::string for get_device_*_string helpers
Removes need to use BufferOwningPtr to avoid memory leaks.
* Rename get_device_info to get_device_info_string
Makes it more obvious that it should only be called for device queries
that return strings.
* Tokenize extensions in is_extension_available
Avoids the potential issue where one extension name is a prefix of
another.
* Throw exception when device info size is 0
is_extension_available is modified to handle errors by throwing
exceptions.

This change reimplements offline compiler invocation, using a new command
line interface that allows the passing of relevant CL device information
to the offline compiler. The information that is passed is as follows:
* CL_DEVICE_ADDRESS_BITS
* CL_DEVICE_EXTENSIONS
* CL_DEVICE_IL_VERSION (with --compilation-mode=spir-v only)
* CL_DEVICE_VERSION
The interface for the offline compiler script is as follows:
usage: cl_offline_compiler --source FILE --output FILE
--cl-device-info FILE --mode MODE
-- [BUILD_OPTIONS [BUILD_OPTIONS ...]]
positional arguments:
BUILD_OPTIONS additional options to pass to the compiler
optional arguments:
--source FILE OpenCL C source file to compile
--output FILE SPIR-V or binary file to create
--cl-device-info FILE OpenCL device info file
--mode compilation mode (spir-v or binary)
The OpenCL C version for compilation is now specified in BUILD_OPTIONS,
as normal for online compilation, i.e. with -cl-std=VERSION.
