Add "replace all" button when doing find and replace

[amrelnaggar]

For #11126.

[ficristo]

I didn't look closely at the code but I wonder if changing the button id could break extensions.
That said this needs at least a test.

[amrelnaggar]

Sorry I've been pretty busy.

I didn't think about extensions. Would it be better if I kept the button id as it was and made a new id for Replace all button? Or unit tests will be enough?

[ficristo]

@amrelnaggar I looked around on the public available extensions and I think this is safe as is. So only the test is needed.

It is only to understand if this is something that would be contributed back from Adobe: @swmitra @madanbn?

[amrelnaggar]

I added the test.

[ficristo]

@amrelnaggar could you merge master so to resolve the conflicts?

[amrelnaggar]

@ficristo All conflicts have been resolved.

If there is anything else needs to be done just let me know.

[ficristo]

Something went wrong. It seems you merged an old version of master.
You can use git rebase -i ... to drop the last two commits and then try to run git fetch upstream and merge again upstream/master
Alternatively you can open a new fresh PR.

[amrelnaggar]

@ficristo I created a new PR #12988.

Closing this PR.
