perf beauty: Move arch/x86/include/asm/irq_vectors.h copy out of the directory used to build perf
It is used only to generate string tables, not to build perf, so move it to the tools/perf/trace/beauty/include/ hierarchy, that is used just for scraping. This is a something that should've have happened, as happened with the linux/socket.h scrapper, do it now as Ian suggested while doing an audit/refactor session in the headers used by perf. No other tools/ living code uses it.

- * Linux IRQ vector layout.
- *
- * There are 256 IDT entries (per CPU - each entry is 8 bytes) which can
- * be defined by Linux. They are used as a jump table by the CPU when a
- * given vector is triggered - by a CPU-external, CPU-internal or
- * software-triggered event.
- *
- * Linux sets the kernel code address each entry jumps to early during
- * bootup, and never changes them. This is the general layout of the
- * IDT entries:
- *
- * Vectors 0 ... 31 : system traps and exceptions - hardcoded events
- * Vectors 32 ... 127 : device interrupts
- * Vector 128 : legacy int80 syscall interface
- * Vectors 129 ... LOCAL_TIMER_VECTOR-1
- * Vectors LOCAL_TIMER_VECTOR ... 255 : special interrupts
- *
- * 64-bit x86 has per CPU IDT tables, 32-bit has one shared IDT table.
- *
- * This file enumerates the exact layout of them:
