perf: Add PERF_BR_NEW_ARCH_[N] map for BRBE on arm64 platform

BRBE captured branch types will overflow perf_branch_entry.type and generic
branch types in perf_branch_entry.new_type. So override each available arch
specific branch type in the following manner to comprehensively process all
reported branch types in BRBE.

  PERF_BR_ARM64_FIQ            PERF_BR_NEW_ARCH_1
  PERF_BR_ARM64_DEBUG_HALT     PERF_BR_NEW_ARCH_2
  PERF_BR_ARM64_DEBUG_EXIT     PERF_BR_NEW_ARCH_3
  PERF_BR_ARM64_DEBUG_INST     PERF_BR_NEW_ARCH_4
  PERF_BR_ARM64_DEBUG_DATA     PERF_BR_NEW_ARCH_5
