File grid view icon too large

[potato1992]

Currently, the default icon size in grid view is too big, as it is refereed in #11902, and to change the icon size in the grid view, I can only modify the $grid-size: 160px; in apps/files/css/files.scss:

#filestable.view-grid:not(.hidden) {
          $grid-size: 160px;
          $grid-pad: 14px;

It's still not perfect solution, as it will be changed back as soon as I upgrade.

Hope to give an option to change the icon size as 'Large icons' 'Medium icons' 'Small icons' like the windows explorer does, another php nas system kodexplorer also supports this function.

Also, please move the menu botton from the bottom to the top, to avoid occupying the limited space to show file name, as demonstrated in this pic.
