drivers: flash: npcx: support GDMA operation for NPCXn and NPCKn

1. Introduced GDMA support for efficient data transfer in the
NPCX FIU QSPI driver.
2. Refactor flash driver mutex handling to enhance concurrency safety,
preventing other threads from preempting erase/write operations during
UMA until mutex release.
