Add a --no-index option to gfxrecon-convert

[marius-pelegrin-arm]

When comparing different traces that are very similar, we may want to convert the traces using the jsonl format to look directly at the call differences.
However, some data in the output of gfxrecon-convert tends to "pollute" the difference, like the block index at the begining of each line.

This commit implements a --no-index option to remove the block index at the begining of each block in the output of gfxrecon-convert

To me, I would like this to be named more like --no-index. And then when you get a few things together, you could make a --bare which enabled those multiple options once you have them in place. I think "bare" alone doesn't make much sense at this point.

@bradgrantham-lunarg, what do you think?

[bartosz-muszarski-arm]

That's actually how this change started, as --no-index.
But since the goal in the end is to make the output diff-friendly, not remove "index" in particular, but anything that might introduce any noise in the diffs in the future, it was renamed to reflect its actual purpose.
That way we can rely on this in automation today.
Would it be really useful to have separate options for these fields anyway?

[MarkY-LunarG]

I personally would like to have the options separate and an option to enable them all as well. Like --bare just forces on all the "messy options". The reason why is I could see people wanting to enable only some of the bare options and always forcing every option at once would be a pain to tweak out. So if you want, do both --no-index and then --bare which only turns on --no-index for now, but will grow in the future.

Hello ! So I put aside the --bare option for the moment and just renamed it --no-index =)
