[NUCLEO_F4x1RE] test MBED_A7 InterruptIn failed

The test failed because it was not possible to switch off an already
active edge detection.
The reason was the GPIO HAL module driver function HAL_GPIO_Init. The
function changes only interrupt or event flags when the EXTI_MODE flag
in GPIO_Init->Mode is set. gpio_irq_set changed the event mode to
EDGE_NONE in gpio_irq_t structure but that doesn't changed the interrupt
and event flags in the CMSIS function because of the missing EXTI_MODE.
Now gpio_irq_set is able to switch off a specific or both edge
detections.
The MBED_A7 test was extended by another test to check if switch off
edge detection is OK.
[DISCO_F407VG] test MBED_A7 InterruptIn failed

- solution similar to [NUCLEO_F4x1RE]
- digital_loop tests "DigitalIn DigitalOut", "DigitalInOut" and
"InterruptIn" are OK

[mbed][KPSDK][K22F][K64F] sw_timer.c seems to be left over from the last version of KSDKand isn't part of the v1.0.0 release. fsl_interrupt_manager.c relies on using KSDK specific startup code and linker scripts which we dont use.
[mbed][exporters][k22f][gcc] Added exporters for uvision, gcc_arm, kds. Known issues are: uvision5 as K22F doesnt seem to be supported with uvision4. gcc_arm and kds - build but blinky led color doesnt behave correctly. Haven't debugged much. python project.py -m K22F -p 25 -i kds [uvision] [gcc_arm] to pick back up.
