0d2c2110 - [allocator] Introduce the abstract class CUDACachingAllocator (#87251)

[allocator] Introduce the abstract class CUDACachingAllocator (#87251) This replaces the manual function pointers, making it easier to write new drop-in allocators. Note that most allocation goes through the Allocator interface, which CUDAAllocator inherits from, and this arrangement avoids adding and additional layer of dispatch along this pathway compared to what existed before.
