Add Kernel Writer driver code to dynamic fusion

* Partially port ElementwiseBinary component to ckw (broadcast not
  supported yet)
* Port Store component to ckw
* Move KernelArgumentsHelpers to ckw_driver/ as it's only used by the
  driver

ckw_driver is a middle layer between dynamic fusion and Compute Kernel
Writer (CKW). It consumes the fused kernel component stream produced by
Dynamic Fusion and uses CKW to write the kernel code complete with all
meta info needed by the runtime to enqueue the kernel.

It consists of two parts:
* Kernel writing: This resides in dynamic_fusion/sketch
* Runtime utilities: This resides in dynamic_fusion/runtime

The integration (separation between DF and CKW) occurs in two places:
* Inside GpuCKWDriver
    global driver that coordinates how the
    final fused kernel code is assembled together alongwith other meta
    info needed by runtime.

* Inside each instantiated IGpuCKWComponentDriver
    component driver that drives CKW to write component-specific code
    or do component-specific configurations

+/** An interface used by @ref GpuCkwDriver to write source code for a kernel component
+ *
+ * There are 3 main architecture layers for using Compute Kernel Writer (Ckw) inside ACL's dynamic fusion module
+ * From top level to bottom level:
+ * | Layer          | Library
+ * ===========================
+ * | dynamic_fusion |   acl
+ * | ckw_driver     |   acl
+ * | ckw            |   ckw
+ *
+ * ckw_driver is a glue layer that directs how fused code is produced using the ckw library
+ *
+ * There are two main groups within ckw_driver:
+ * - @ref GpuCkwDriver is a global driver that coordinates how the final fused code along with all the info necessary
+ *   for run time execution is produced using ckw
+ * - Various classes implementing @ref IGpuCkwComponentDriver is a component driver that directs ckw to generate kernel component code (e.g. activation, store etc.)
+ *
+ * The overall flow goes like this:
+ * In dynamic_fusion module, @ref GpuLogicalKernel instantiates a @ref GpuCkwDriver from a @ref GpuKernelComponentGroup
+ * The logical kernel then uses the global driver's various interfaces to generate the code info.
+ * In particular, the @ref GpuCkwDriver::get_code() interface will call into each @ref IGpuCkwComponentDriver::write_component_code()
