Add TFM flash partitions to v2m_musca_b1_musca_b1_ns board

[Copilot]

The v2m_musca_b1/musca_b1/ns board failed to build with TFM-enabled tests due to missing device tree partition definitions required by the TFM module at cmake configuration time.

Changes:

• Added flash partition table to boards/arm/v2m_musca_b1/v2m_musca_b1_musca_b1_ns.dts:
  • slot0_partition (256KB) - Secure image primary
  • slot0_ns_partition (512KB) - Non-secure image primary
  • slot1_partition / slot1_ns_partition - Secondary slots for updates
  • scratch_partition (96KB) - MCUBoot scratch area
• Set zephyr,code-partition to &slot0_ns_partition in chosen node
• Added flash properties: compatible = "soc-nv-flash", erase-block-size = <4096>, write-block-size = <4>

Partition layout follows the standard TFM multi-image boot scheme used by mps2/an521 and other ARM TFM reference boards, fitting within the board's 1664KB available eFlash at 0xa070000.
