CMake: link TF-M for both memory partition

This patch introduces the MCUBOOT_NO_SWAP compiler switch:
  - Default value is False to preserve swapping functionality to be
    default
  - When disabling it then TF-M is built in one instance:
    - tfm_sign.bin:   linked to run in XIP mode from slot 0 memory
      partition
  - When enabling it then TF-M is built in two instances:
    - tfm_sign_0.bin: linked to run in XIP mode from slot 0 memory
      partition
    - tfm_sign_1.bin: linked to run in XIP mode from slot 1 memory
      partition
