fix(material/button): prevents mat-icon svg size and visibility issues (#32338)

Updates Angular Components Button component styling for mat-icon-buttons and all
mat-fab-button variants. Only includes min-height of min-content for icons in
other button variants so that when displaying svg icons such as fontawesome
the height fits into the icon and is visible in safari browsers
