CMake: Add post build operation support

A CMake custom target, mbed-post-build, is added as a dependency of the
application CMake target if a Mbed target adds a CMake custom target
named mbed-post-build-bin. mbed-post-build-bin is added as a dependency
of mbed-post-build. mbed-post-build-bin depends on the application binary.
This is done so a CMake custom command that executes post-build can be added.

The Python scripts that implement the operations have been modified to add
CLI entry points so they can be called from CMake. Dependency on the old
tool has been removed on those scripts by passing them exactly what they
require instead of passing old tool Python objects. A consequence of that
was to slightly amend how the old tool calls some of those Python modules.

Support has only been added for Mbed targets that currently have a requirement
for post build operations. This includes: LPC1114, LPC1768, ARCH_PRO, LPC54114,
LPC546XX, FF_LPC546XX, CY8CKIT064B0S2_4343W, CYTFM_064B0S2_4343W, CYSBSYSKIT_01

The following targets are not supported as TFM support is not yet included:
ARM_MUSCA_B1, ARM_MUSCA_B1_NS, ARM_MUSCA_S1, ARM_MUSCA_S1_NS.
