x86/irq: Define trace events conditionally

Browse Source 
[ Upstream commit 9de7695925 ]

When both of X86_LOCAL_APIC and X86_THERMAL_VECTOR are disabled,
the irq tracing produces a W=1 build warning for the tracing
definitions:

  In file included from include/trace/trace_events.h:27,
                 from include/trace/define_trace.h:113,
                 from arch/x86/include/asm/trace/irq_vectors.h:383,
                 from arch/x86/kernel/irq.c:29:
  include/trace/stages/init.h:2:23: error: 'str__irq_vectors__trace_system_name' defined but not used [-Werror=unused-const-variable=]

Make the tracepoints conditional on the same symbosl that guard
their usage.
