Description

This PR add the parameter FullWidth in MudIconButton and MudToggleIconButton.
FullWidth add the class mud-width-full on the button to stretch it.

Visual example :

<p>MudToggleIconButton without FullWidth</p>
<div style="background-color: rgba(51, 170, 51, .05)">
    <MudToggleIconButton Icon="@Icons.Material.Filled.AlarmOff" Color="@Color.Error"
                         ToggledIcon="@Icons.Material.Filled.AlarmOn" ToggledColor="@Color.Success" />
</div>

<br />

<p>MudToggleIconButton with FullWidth</p>
<div style="background-color: rgba(51, 170, 51, .05)">
    <MudToggleIconButton Icon="@Icons.Material.Filled.AlarmOff" Color="@Color.Error"
                         ToggledIcon="@Icons.Material.Filled.AlarmOn" ToggledColor="@Color.Success"
                         FullWidth />
</div>

From the issue #9811.
