PromptDialog with long subtitle

I am unable to reproduce this using newest kirigami + kirigami-gallery

This is the prompt dialog code:

```qml

    Kirigami.PromptDialog {
        id: textPromptDialog
        title: "New Folder"
        subtitle: "Long subtitle aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"

        standardButtons: Kirigami.Dialog.NoButton
        customFooterActions: [
            Kirigami.Action {
                text: qsTr("Create Folder")
                icon.name: "dialog-ok"
                onTriggered: {
                    showPassiveNotification("Created");
                    textPromptDialog.close();
                }
            },
            Kirigami.Action {
                text: qsTr("Cancel")
                icon.name: "dialog-cancel"
                onTriggered: {
                    textPromptDialog.close();
                }
            }
        ]

        FormCard.FormTextFieldDelegate {
            label: qsTr("Folder name:")
            leftPadding: 0
            rightPadding: 0
        }
    }

```

It works as expected if the subtitle is known at creation time.

Minimal example to reproduce the problem:
```qml
    Kirigami.PromptDialog {
        id: textPromptDialog
        title: "Title"
        subtitle: "empty"
        Component.onCompleted: {
            subtitle = "A long subtitle which should change the width of the PromptDialog"
        }
    }
```

Thanks, i could repro it now!

Use TextEdit instead of QQC2.TextArea in SelectableLabel, add context menu to SelectableLabel

SelectableLabel wont resize properly when using QQC2.TextArea, likely due to TextArea having it's own
resizing and background handling. 

TextEdit is handled more like a Label is, so it resizes correctly. We just have to manually make it use the proper colors, which was doable with Kirigami.

SelectableLabel also has its own, smaller context menu now.

Create SelectableText, deprecate SelectableLabel

This creates a new SelectableText element that is supposed
to replace SelectableLabel due to resizing issues.

SelectableLabel uses TextArea, which has features Label does
not really need. TextArea also has issues when resizing,
since the ImplicitSize resizing is disabled after the initialization.
This can cause problems with dynamically changing content, where
the TextArea size wont update based on the content.

TextEdit has ImplicitSizes as read-only, but it resizes
automatically based on the text content. It's wrapped inside a Control.

SelectableText also has a simpler context menu, with only
Copy and SelectAll buttons.

I chose the name SelectableText since this is based on TextEdit, not
label.

PromptDialog: Port to SelectableText

SelectableLabel does not resize correctly due to using TextArea, if the
text inside the dialog is dynamically changed. This is because TextArea disables resizing the implicitSizes after initialization.

Use the new SelectableText item instead, which works with
dynamic resizing.

Modify SelectableLabel to use TextEdit instead

Discussion: https://invent.kde.org/frameworks/kirigami/-/issues/91

SelectableLabel wont resize properly when using QQC2.TextArea, due to
TextArea having implicitSize resizing disabled after the initial size.

TextEdit is handled more like a Label is, so it resizes correctly.
Wrapping it inside Control and exposing the expected properties and
signals it should be a drop-in replacement for the old TextArea based
SelectableLabel.

SelectableLabel also has its own, smaller context menu now.

Note that this may be API breaking so we need to do a lot of testing.
