  2. executor: Add AFLExecutorInterface class 

    This commit adds `AFLExecutorInterface` class to represent required
functions for an executor to support AFL-compatible algorithms. This
class accepts `std::shared_ptr<T>` of any class `T` as long as it
satisfies the function requirements. This behavior mimics Rust's trait
objects [1] using type erasure.

  3. executor: Add LibFuzzerExecutorInterface class 

    This commit adds `LibFuzzerExecutorInterface` class to represent
required functions for an executor to support libFuzzer-compatible
algorithms. This class accepts `std::shared_ptr<T>` of any class `T` as
long as it satisfies the function requirements. This behavior mimics
Rust's trait objects [1] using type erasure.

  4. build: Change to use AFLExecutorInterface for AFL family 

    This commit changes to use `AFLExecutorInterface` instead of using
`NativeLinuxExecutor` directly so that the algorithms are independent
from actual executor type. Note that this commit does not affect
algorithm behaviors and the executor is still fixed to
`NativeLinuxExecutor`.
