interrupts: simplify position of sw ISR table

We now place the linker directives for the SW ISR table
in the common linker scripts, instead of repeating it
everywhere.

The table will be placed in RAM if dynamic interrupts are
enabled.

A dedicated section is used, as this data must not move
in between build phases.
