Add global GPIO support for ADC_PINS and PWM_PINS macros

When adc_pin_gpios or pwm_pin_gpios are used without digital_pin_gpios
(global-GPIO mode), the DIGITAL_PIN_GPIOS_FIND_PIN macro is not available.
This commit adds conditional compilation to use ZARD_GLOBAL_GPIO_NUM in
global-GPIO mode, which derives the global GPIO number from the GPIO
specifier (port and pin).

Fixes compilation issue when using adc-pin-gpios or pwm-pin-gpios in
global-GPIO mode.
