Vulkan: Add Pipeline blob cache per chunk CRC check Each chunk now have it's own CRC value, that is calculated starting from beginning of the data up to the end of the chunk. This way last chunk will have CRC of the entire data, avoiding calculating it separately. The `GenerateCRC32()` was splint into `InitCRC32()` and `UpdateCRC32()` function, which supports calculating running CRC32. Calculating CRC this way has some performance hit, when using many small chunks. Increasing chunk size to at least 1 MB almost negates any overhead from running `UpdateCRC32()` multiple times. On S921B with locked frequencies, calculating CRC for 89 MB of data using single call took 7.13 ms and 13.34 ms, when using multiple calls. However even this difference is negligible, because compressing 291 MB of data to 89 MB took 9.22 seconds.
