add support for capturing SPIR-V files for programs created from IL

[bashbaug]

Description of Changes

• Adds support for capturing SPIR-V files for programs created from IL for replay.
• Adds the validation functionality to the run script. This allows validation without using the top-level capture_and_validate script.
• Adds missing call to clFinish that could cause the wrong buffers to be dumped, especially for programs using out-of-order queues.

Testing Done

Tested with an OpenCL conformance test and a SYCL program that creates a program from IL. Was successfully able to replay and validate the captured program.

[bashbaug]

@Pennycook this should automatically capture the SPIR-V files for you so you don't need to extract them from the device binary.
