bpf: there is no ldinddw nor ldabsdw instructions

Browse Source 
There are no legacy ldind nor ldabs BPF instructions with BPF_SIZE_DW.
For some reason we were (incorrectly) supporting these.  This patch
updates the opcodes so the instructions get removed and modifies the
GAS manual and testsuite accordingly.

See discussion at
https://lore.kernel.org/bpf/110aad7a-f8a3-46ed-9fda-2f8ee54dcb89@linux.dev

Tested in bpf-uknonwn-none target, x86-64-linux-gnu host.

include/ChangeLog:

2024-01-29  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* opcode/bpf.h (enum bpf_insn_id): Remove BPF_INSN_LDINDDW and
	BPF_INSN_LDABSDW instructions.

opcodes/ChangeLog:
