toolchain/toolchain-external: update Arm AArch64 toolchain 10.3-2021.07

Update to gcc 10.3, gdb 10.2, binutils 2.36.1, glibc 2.33.

Remove BR2_TOOLCHAIN_HAS_NATIVE_RPC since the support for obsolete
RPC was finally dropped in glibc in 2.32 (2020-08-04).

See "Release Note":
https://developer.arm.com/open-source/gnu-toolchain/gnu-a/downloads#

Tested with qemu_aarch64_virt_defconfig.
