audio: use xtensa/core-isa headers for HiFi builds

Use <xtensa/config/core-isa.h> consistently in HiFi FIR/SRC/ARIA and
format headers instead of <xtensa/config/defs.h>.

This avoids compiler-specific include probing and keeps build behavior
identical across Cadence and upstream LLVM toolchains, since Zephyr SDK
provides core-isa headers consistently for Xtensa targets.
