BE32 binaries are no longer supported for ARMv7 and later, and
therefore for aarch64eb.

Reject them with ENOEXEC, rather than causing illegal instruction
exceptions due to unexpected binary format.

Not only the kernel thread, but also the userland PAC keys
(APIA,APIB,APDA,APDB,APGA) are now randomly initialized at exec, and switched
when context switch.
userland programs are able to perform pointer authentication on ARMv8.3+PAC cpu.

reviewd by maxv@, thanks.

PR port-arm/54702

Add support for earmv6hf binaries on COMPAT_NETBSD32 for aarch64:

- Emulate ARMv6 instructions with cache operations register (c7), that
  are deprecated since ARMv7, and disabled on ARMv8 with LP64 kernel.

- ep_machine_arch (default: earmv7hf) is copied from executables, as we
  do for mips64. "uname -p" reports earmv6hf if compiled for earmv6hf;
  configure scripts etc can determine the appropriate architecture.

Many thanks to ryo@ for helping me to add support of Thumb-mode,
as well as providing exhaustive test cases:

  https://github.com/ryo/mcr_test/

We've confirmed:

- Emulation works in Thumb-mode.
- T32 16-bit length illegal instruction results in SIGILL, even if
  it is located nearby a boundary b/w mapped and unmapped pages.
- T32 32-bit instruction results in SIGSEGV if it is located across
  a boundary b/w mapped and unmapped pages.
