rename DUAL_GYRO to MULTI_GYRO (debug mode) (betaflight#846)

feat: add MULTI_GYRO debug mode support for firmware 4.6.0+

Add version-gated DUAL_GYRO to MULTI_GYRO debug mode renaming with display names
supporting up to 4 gyros. Debug modes show proper axis labels like 'Gyro 1 Diff [roll]'
and maintain backward compatibility with existing DUAL_GYRO modes.
