arm64: Set CONFIG_MULTI_IRQ_HANDLER 



arm has an optional MULTI_IRQ_HANDLER, which arm64 copied but didn't make
optional.  The multi irq handler infrastructure has been copied to generic
code selectable with a new config symbol. That symbol can be selected by
randconfig builds and can cause build breakage.

Introduce CONFIG_MULTI_IRQ_HANDLER as an intermediate step which prevents
the core config symbol from being selected. The arm64 local config symbol
will be removed once arm64 gets converted to the generic code.
