Component: Multiselect Component Close Button Accessibility Issues - Close Button is empty + Screen Reader reads 'Unlabeled button'

[willmca]

Describe the bug

The Multiselect component's close button is not currently passing 508 accessibility tests, because the button is 'empty'. I have attached a screenshot showing the error thrown by WAVE 508 testing tool. For accessibility purposes, button must have content.

Additionally, when utilizing a screen reader, the button to close the multiselect reads as 'unlabeled button'. This provides a screen reader user no information about what the button does.

Steps to reproduce the behavior

Note - Tools used for accessibility testing are WAVE accessibility evaluation tools browser extension and JAWS Screen Reader

To replicate Empty Button error with WAVE tool:

1. Navigate to any Multiselect component
2. Open the panel
3. Run the WAVE tool, you will see the empty button 508 accessibility error

To replicate Screen Reader reading unlabeled button

1. Turn on a screen reader
2. Navigate to any Multiselect component
3. Open the panel
4. Use keyboard navigation to focus on the (x) button used to close the panel

Expected behavior

There should not be an error for 'empty button' when running accessibility tests on the component. Additionally, when using a screen reader, the screen reader should provide a description for what the button does when the user focuses on the button.
