NorFlashDxe in ArmPlatformPkg is used in two different ways:
- by emulated QEMU based platforms that use its NOR flash emulation
  which is based on versatile express
- by physical ARM platforms under Platform/ARM in edk2-platforms.

In order to improve support for the former use case, let's first split
off the latter and give them their own version of the driver.

  Platform/ARM/BootMonFs: drop spurious dependency on ArmPlatformPkg
  Platform/ARM: create local definition of NorFlashPlatformLib
  Platform/ARM: clone NorFlashDxe from ArmPlatformPkg
  Platform/ARM: switch to local version of NorFlashDxe drivers
