This commits implements the simpliest class wrapping the basic gpio interrupt functionalities. - Setting an interrupt on a given GPIO and providing a callback function - enabling the interrupt on a given GPIO - disabling the interrupt on a given GPIO The gpio_intr_cxx example is added as a sandbox for testing during development
this commit adds: - gpio_common_cxx.hpp where the GPIONum and GPIOExceptions types are defined to make it accessible on both gpio_intr_cxx.hpp and gpio_cxx.hpp - the strong type GPIOIntrType - the conversion function from GPIOIntrType to C driver gpio_intr_type - the conversion function from GPIONum to C driver gpio_num_t
- create GPIOIsrFlag class that builds and provides ISR flags to pass to gpio_install_isr_service()
…ven GPIO number this function will also disable de interrupts on this GPIO
…thods in GPIO_intr - remove reference to GPIO_Intr from gpio_cxx.hpp to lower binary size when interrupt is not used. - gpio_intr prefix removed as it is redundant with the name of the Class. - the callback table now accepts a list a callback ona given GPIO number. - when first callback is added on a given GPIO, the generic callback is registered to the driver. - when the last callback is removed on a given GPIO, the generic callback is de-registered from the driver
…. Move isr service related method to GPIOIsr - Remove conversion functions and use get_value<>() instead - GPIOIntr is tied to a GPIO number, the user handles instances of the classes itself - GPIOIsr provides function to start and stop ISR service from the driver (WIP)
this commit also move hldr_bounce and driver_handler methods to the provate section of GPIOIntr.

This will force the user to have a GPIO input setup when using the interrupt functionalities.
The new constructor takes gpio number, pull mode and driver strength as parameters. This constructor by used in GPIOIntr constructor.

Create 3 senarios running on 3 different threads. In each scenario, a GPIOIntr instance is created and 1(or 2) callback(s) is(are) registered. the example showcases the usage of lambda function, static function and non static member function as callback for GPIO interrupts.

Implement the GPIO interrupt functionalities based on the esp-idf gpio driver.
