Update perf util arm64_exception_types.h to match the exception class
macros defined in tools/arch/arm64/include/asm/esr.h. This ensures
consistency between perf tooling and the kernel header definitions for
ESR_ELx_EC_* values.
In v2, ESR_ELx_EC_OTHER and ESR_ELx_EC_GCS, which were missing in v1, were
included.
