arm: Remove lazy tlsdesc initialization related code

Lazy tlsdesc initialization is no longer used in the dynamic linker
so all related code can be removed.

	* sysdeps/arm/dl-machine.h (elf_machine_runtime_setup): Remove
	DT_TLSDESC_GOT initialization.
	* sysdeps/arm/dl-tlsdesc.S (_dl_tlsdesc_lazy_resolver): Remove.
	(_dl_tlsdesc_resolve_hold): Likewise.
	* sysdeps/aarch64/dl-tlsdesc.h (_dl_tlsdesc_lazy_resolver): Remove.
	(_dl_tlsdesc_resolve_hold): Likewise.
	* sysdeps/aarch64/tlsdesc.c (_dl_tlsdesc_lazy_resolver_fixup): Remove.
	(_dl_tlsdesc_resolve_hold_fixup): Likewise.
