arm: irq: fail build if IRQ_CONNECT is used with ZLI

Commit 3b8e1fa updated the documentation
to mention explicitly that ZLI must be registered using IRQ_DIRECT_CONNECT.

Update the ARM IRQ macros such that attempts to register a ZLI using
IRQ_CONNECT becomes a build failure instead of silently succeeding.
