freertos: Remove critical nested macros

This commit removes the following critical nested macros as follows:

- portENTER_CRITICAL_NESTED()
- portEXIT_CRITICAL_NESTED()

They are replaced with portSET_INTERRUPT_MASK_FROM_ISR() and
portCLEAR_INTERRUPT_MASK_FROM_ISR() which are the proper FreeRTOS interfaces.

Created a portmacro_deprecated.h for each port to contain deprecated API
that were originally from portmacro.h
