cmake: Add MAX32657 platform and board config

[adi-ramonimbao]

Pull Request Description

This PR adds build system support for the MAX32657, and board config files for the MAX32657EVKIT:

• Board preset and defconfig:
  • board_configs/maxim/CMakePresets.json: new max32657evkit preset
  • board_configs/maxim/max32657evkit_defconfig: default configuration enabling CAPI only
• MAX32657 platform build files:
  • drivers/platform/maxim/max32657/CMakeLists.txt: pulls in the MSDK PeriphDriver sources, and memory layout definitions
  • drivers/platform/maxim/max32657/memory_layout.cmake: memory layout file
  • drivers/platform/maxim/CMakeLists.txt: do not include maxim_init.c and maxim_delay.c when using CAPI
  • drivers/platform/maxim/toolchain.cmake: add an if() guard to allow overriding of OPENOCD_INTERFACE since you can use also OpenOCD with JLink interface on the MAX32657EVKIT.
• CAPI CMake wiring:
  • capi/platform/maxim/max32657/CMakeLists.txt: pulls the necessary Maxim CAPI drivers
  • capi/platform/maxim/CMakeLists.txt: selects the max32657 backend when TARGET == max32657

Must be merged after #3271.

V2:

• Change if() guard around non-CAPI maxim_init and maxim_delay

[adi-ramonimbao]

V3:

• Add an if() guard for setting the OpenOCD interface in Maxim toolchain.cmake
• Set interface/jlink.cfg as the OpenOCD interface for the MAX32657EVKIT.

V4:

• Add capi_wdt.c source if CAPI_WDT is enabled in capi/CMakeLists.txt
• Set CONFIG_CAPI_WDT=y on MAX32657EVKIT board definition
• Rebase

EDIT: I previously added a new entry for CAPI_WDT to capi/Kconfig, but realized it's not part of the main branch yet. It still depends on getting #3206 merged. I will update the PR once merged.

V11:

• Removed capi/CMakeLists.txt again.
• For some reason drivers/platform/maxim/max32657/CMakeLists.txt and drivers/platform/maxim/max32657/memory_layout.cmake were missing in the latest push. Added them again.
