Documentation inconsistency

[KeilChris]

On the page https://arm-software.github.io/CMSIS_6/latest/Core/startup_c_pg.html#startup_c_sec, we state that: "The naming convention for the interrupt handler names is <interrupt_name>_IRQHandler. "

This is not 100% true! There's the exception of the SVCall_IRQn vs. the SVC_Handler. It seems that Microchip tripped over this. They called their SVC handler "SVCall_Handler", but RTX does not like this for example.

I suggest to create an explicit table of IRQ vs. Handler.
