scripts/extract/globals: treat node alternate names as 'aliases'

Treat new generated dtc element 'alt-name' as usual aliases. Aim is not to duplicate generation of node elements but provide pointers using generic alternate names. For instance, defining following overriding node: arduino_i2c : i2c1 {}; Will generate following definition: #define ARDUINO_I2C_LABEL ST_STM32_I2C_V1_40005400_LABEL Then 'ARDUINO_I2C_LABEL' could be use a generic binding.
