 Eviction in in-memory cache is disabled by default but can be controlled by SYCL_IN_MEM_CACHE_EVICTION_THRESHOLD
 environment variable. The threshold is set in bytes and when the cache size exceeds the threshold the eviction process is initiated. The eviction process is based on LRU strategy. The cache is walked through and the least recently used items are deleted until the cache size is below the threshold.
-To implement eviction for in-memory cache efficiently, we store the programs in a linked-list, called eviction list. When the program is first added to the cache, it is also added to the back of the eviction list. When a program is fetched from cache, we move the program to the end of the eviction list. This way, we ensure that the programs at the beginning of the eviction list are always the least recently used.
-When adding a new program to cache, we check if the size of the program cache exceeds the threshold, if so, we iterate through the eviction list starting from the front and delete the programs until the cache size is below the threshold. When a program is deleted from the cache, we also evict its corresponding kernels from the kernel and fast kernel cache.
