[llvm-mc] Add --hex to disassemble hex bytes

`--disassemble`/`--cdis` parses input bytes as decimal, 0bbin, 0ooct, or
0xhex. While the hexadecimal digit form is most commonly used, requiring
a 0x prefix for each byte (`0x48 0x29 0xc3`) is cumbersome.

Tools like xxd -p and rz-asm use a plain hex dump form without the 0x
prefix or space separator. This patch adds --hex to disassemble such hex
bytes with optional whitespace.

```
% rz-asm -a x86 -b 64 -d 4829c34829c4
sub rbx, rax
sub rsp, rax

% llvm-mc -triple=x86_64 --cdis --hex --output-asm-variant=1 <<< 4829c34829c4
        .text
        sub     rbx, rax
        sub     rsp, rax
```
