arm-bsp/corstone1000: Support multi-payload capsule generation

- Add 'CAPSULE_SELECTED_COMPONENTS' to enable filtering of firmware
  components during capsule generation. Only components listed in
  'CAPSULE_SELECTED_COMPONENTS' will be included in the final capsule
  image.

- Introduce CAPSULE_EXTRA_ARGS to allow passing additional arguments.
  '--capflag PersistAcrossReset' to retain capsule across reboots.

- Payload selection is now controlled via the KAS YAML configuration
  (corstone1000-image-configuration.yml), allowing per-image control
  over which firmware components are included.

- With the introduction of multiple payload support, 'CAPSULE_VERSION'
  no longer represents the firmware version itself but is instead
  used for naming the capsule and assigning a common version to all
  payloads to simplify testing.

- Use EDK2 tool to switch from single FMP capsule generation to multiple
  FMP capsules using a JSON-based configuration. This removes the need
  for manually combining firmware images into a .nopt image.

- Remove legacy nopt image creation logic, as each firmware binary is
  now handled individually. Components no longer need to be merged.
  Deploy task was removed with nopt logic.

- Generate dummy.bin for EDK2 tool compatibility. EDK2 requires
  at least one input file for each payload.

- Added dependency on  to  to ensure images are signed before capsule
  generation.

- Add CAPSULE_LOWEST_SUPPORTED_VERSION to
  corstone1000-image-configuration.yml.It in the same file where
  the firmware version (FW_VERSION) is defined, ensuring a unified
  location for version-related metadata. This value was chosen to
  be equal to the firmware version to represent a downgrade
  scenario (from version 6 to version 5) during testing.

- CAPSULE_HARDWARE_INSTANCE is set to "1" by default (instead of 0),
  indicating the first hardware.
