• Adds boot, update and rollback emulator tests on m33mu for MCX W71, RW612, nRF54L15, nRF54LM20 and nRF5340. Each runs a
  plain, TrustZone and ML-DSA config where the target has them.
• Adds the MCXN947 plain, TrustZone and ML-DSA configs and the LPC55S69 ML-DSA config to their existing emulator workflows.
• One commit per device, each with its own workflow file. The first two commits are shared test.sh fixes.
• The MCX W71 test app drives FMU0 and uses the LPUART1 console the HAL uses.
• The RW612 test app programs through the boot ROM FlexSPI NOR driver.
• The nRF54L test app writes through the RRAMC.
• The MCXN947 test app now builds for non-secure and plain configs, not only the secure payload.
• New ML-DSA example configs for MCX W71, RW612, nRF54L15, nRF54LM20, nRF5340, MCXN947 and LPC55S69, each with a build job.
• The MCXN example partitions are now 64 KB and aligned to the 8 KB flash sector. The old 0xB000 layout put the update
  partition off a sector boundary.
• test.sh stops early with a clear message when the m33mu binary lacks the target's CPU model.
• Tested with test.sh scenarios A, B and C on all 22 configs inside the wolfboot-ci-m33mu container, against an m33mu build
  with the matching models.
• Depends on danielinux/m33mu wolfboot-targets. This stays a draft until the wolfboot-ci image is rebuilt with it.

🟡 Changes recommended

The Makefile omits NVM_FLASH_WRITEONCE when compiling libwolfboot.c, creating a trailer-protocol mismatch with the bootloader that can cause update triggers to be lost.

What changed in this PR

Expands wolfBoot’s m33mu emulator coverage for boot, update, and rollback across NXP and Nordic targets, including plain, TrustZone, and ML-DSA configurations where supported. The new workflows depend on a CI image containing the matching m33mu models.

Changes:

• Adds device-specific workflows and extends existing emulator and configuration-build matrices.
• Adds RW612 and nRF54L test apps, flash support, and UART and memory-layout adjustments.
• Adds ML-DSA example configurations, aligns MCXN partitions, and improves emulator compatibility checks.
