components/esp_common: added esp_macros.h that aims to hold useful macros

Browse Source 
esp_common/esp_compiler: renamed esp_macros file to a more specific one

esp_common/esp_compiler: removed CONTAINER_OF macro, it was a duplicate

components/freertos: placed likely macros around port and critical sections

component/freertos: placed likely macros on lists module

components/freertos: placed unlikely macros inside of assertion points, they likely wont fail

components/freertos: added likely macros on queue modules

FreeRTOS queues are one of most hot code path, because to queues itself tend to
be used a lot by the applications, besides that, queues are the basic primitive
to form both mutexes and semaphores, The focus here is to place likely
macros inside lowest level send and receive routines, since they're common
from all kobjects: semaphores, queues, mutexes and FR internals (like timer queue)

components/lwip: placed likely/unlikey on net-interfaces code

components/fatfs: added unlikely macros on disk drivers code

components/spiffs: added unlikely macros on low level fs driver

components/freertos: added likely/unlikely macros on timers and ticker

freertos/event_group: placed likely/unlikely macros on hot event group code paths

components/sdmmc: placed likely / unlikely macros on lower level path of sdmmc

components/bt: placed unlikely macros around bt HCI functions calling

components/lwip: added likely/unlikely macros on OS port code section

components/freertos: fix code style on tick handler
