Describe the bug

Using SelectEntry with a long PlaceHolder looks odd because the ActionItem to open the dropdown is rendered partially over the PlaceHolder text.

How to reproduce

1. Run example code
2. Hover with mouse over ActionItem to open dropdown
3. See overlap as shown in screenshot

Screenshots

Example code

package main

import (
	"fyne.io/fyne/v2/app"
	"fyne.io/fyne/v2/container"
	"fyne.io/fyne/v2/widget"
)

func main() {
	a := app.New()
	w := a.NewWindow("PlaceHolder SelectEntry Overlap Test")

	e := widget.NewSelectEntry([]string{})
	e.PlaceHolder = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."

	w.SetContent(container.NewCenter(e))
	w.ShowAndRun()
}

OK I am working on this and realised that perhaps we were mistaken in making those buttons so small anyway. So here is the result of what I think is possibly a better arrangement. It's much more space than before but keen for feedback before I hope a PR.

This is the 3 possible combinations of accessory and validation that a (Select)Entry can have.
Note of course the buttons are hovered to show the extents now are approx min-size instead of icon size.

Makes absolute sense to me and looks good as well.

Sorry for the delay, there is finally a PR open with that code!

Fixed on develop for v2.6.0.
As noted on the PR this was deemed a behaviour change so won't be in the 2.5.x release series.
