perf/core: Expand PERF_EVENT_FLAG_ARCH

Two hardware event flags on x86 platform has overshot PERF_EVENT_FLAG_ARCH
(0x0000ffff). These flags are PERF_X86_EVENT_PEBS_LAT_HYBRID (0x20000) and
PERF_X86_EVENT_AMD_BRS (0x10000). Lets expand PERF_EVENT_FLAG_ARCH mask to
accommodate those flags, and also create room for two more in the future.
