arch: arm: introduce support for dynamic direct interrupts

Browse source 
With this commit we add support for Dynamic Direct interrupts
for the ARM Cortex-M architecture. For that we introduce a new,
user-enabled, Kconfig symbol, DYNAMIC_DIRECT_INTERRUPTS.

help
Direct interrupts are designed for performance-critical interrupt
handling and do not go through all of the common interrupt handling
code. This option enables the installation of interrupt service
routines for direct interrupts at runtime.
Note: this requires enabling support for dynamic interrupts in the
kernel.
