Respect revealIfOpen setting when opening editors with Quick Open

[mkcode]

This PR fixes an issue where there is inconsistent behavior between opening file and editors when using Quick Open with respecting the workbench.editor.revealIfOpen setting.

Before this PR:

• Using Quick Open to open a file does respect the workbench.editor.revealIfOpen setting.
• Using Quick Open to open an editor ( 'edt' prefix ) does not respect the workbench.editor.revealIfOpen setting.

After this PR:

• Using Quick Open to open a file does respect the workbench.editor.revealIfOpen setting.
• Using Quick Open to open an editor ( 'edt' prefix ) does respect the workbench.editor.revealIfOpen setting

This PR is tangentially related to #94705 where there has been lots of discussion.

I made an alternative implementation which introduces a unique setting workbench.editor.alwaysOpenInActiveGroupFromQuickOpen here: 02d4d73 But IMO, it is more clean to use the existing setting to create consistent behavior in this case, rather than introducing a new more granular setting.

This is by design: the list of editors in quick pick should focus on the editor you pick in the right group picked. Consider this picker like editor tabs: if you click on an editor tab you would not expect another editor to open, irrespective of the reveal if opened setting.

@bpasero - Ok. It looks like this PR would change the default behavior of VSCode which I believe would be unacceptable. I would still very much like an opt-in setting to enable this behavior, which I created here: 02d4d73 Would you prefer me to add this commit to this PR or open a new one?
