Add AriaRole Enum to /src/enumerations

[snsavage]

We've been adding Aria roles to various places in projects and in doing so have created an enum with Aria roles. Our initial enum implementation is:

export enum AriaRole {
    List = "list",
    ListItem = "listitem",
    Search = "search",
    Status = "status",
    TabList = "tablist",
    Tab = "tab",
    TabPanel = "tabpanel",
}

The enum should be added to .

Move information about other Aria roles can be found at .
