west.yml: MCUboot synchronization from upstream

[nordicjm]

Update Zephyr fork of MCUboot to revision:
212997395ed34ff1721f5f4461b800e81abeb68d

Brings following Zephyr relevant fixes:

• 21299739 zephyr: firmware/single_loader: Fix compile warning
• a88e2293 zephyr: sysflash: Fix if condition for zephyr applications
• 2a74a2b5 zephyr: io: add 'io_led_set()'
• 8c6c6701 zephyr: io: include 'bootutil_log.h' and declare log module membership
• d99154f4 zephyr: rename 'led_init()' to 'io_led_init()'
• c43a20fd boot: zephyr: add support for mimxrt1040_evk

Notes on process:

1. The MCUboot update from mcu-tools/mcuboot/main with the SHA used in west.yaml is already synchronized to zephyrproject-rtos/mcuboot/upstream-sync branch, and is available in the Zephyr fork of MCUboot.
2. The [DNM] on this PR should be kept until the PR passes all tests and is accepted.
3. Once the PR passes all tests and gets accepted, the upstream-sync branch should be fast-forward merged to zephyrproject-rtos/mcuboot/main branch and [DNM] should be removed.
4. After the main branch gets updated, this PR does not require further changes and should be merged as is.

Fixes #66248

@andysan this should resolve your issue

I can confirm that this fixes #66248 for me, including setting boot loader information in the retention area (in single-slot mode) which I was about to file as a separate bug report.
