Fix renaming files with long names in GridViewBrowser

[gave92]

This PR fixes the issue with renaming files with long names when in GridViewBrowser. I'm using ListView + WrapPanel from windows community toolkit from instead of GridView.
Fixes #657

@yaichenbaum This PR changes selection view, is it acceptable?

Edit: Button reveal effect is disabled
Edit: I like new folder icon margin

[gave92]

@yaichenbaum I'm having second thoughts on this: do you know if WrapPanel is virtualized? If it's not performance might be bad on large folders

[yaira2]

@gave92 Virtualization is very important, what if we built this off items repeater?

[gave92]

I've read that in the latest version of Community Toolkit they rebuilt the WrapPanel to use items repeaters, but I'm not sure if that version is out yet. See here.

Edit: it's in pre-release in version 6.1

Edit2: i'm taking this back as the solution is not viable due to WrapPanel not being virtualized

[gave92]

Ok I approached this differently.

Solution: just use simple a popup with the TextBox
Pros: little code changes, nice "overlay" appearance over the next line items
Todo: perhaps add the "x:Load=False" attribute to the popup? done

@yaichenbaum I'm not using ItemsRepeater as you loose many features GridView gives you (e.g. Selection)

Can you share a screenshot of the new behavior?

[gave92]

[yaira2]

Looks good, does the reveal affect still work?

[gave92]

The revel effect between the files/folders? Yes, I didn't have the mouse on the list in the screenshot

[yaira2]

I found a bug

• Start renaming a file
• Type in a new name
• Cancel the rename operation
• Start a rename operation again and the text from last time is still there.

[gave92]

The current app does the same thing. Can you confirm?
Btw should be easy to fix, should I do it in this PR?

[yaira2]

@gave92 It can be done in a different PR.

@gave92 Can you resolve the merge conflict?
