feat(web): shared breadcrumbs component for folders and tags

[ben-basten]

Description

Create a shared Breadcrumbs component that both Tags and Folders use to show hierarchy.

Benefits of the new breadcrumbs component include:

• Consistent UX for both folders and tags. For example, both experiences now have a button to navigate up one level.
• All breadcrumbs are links instead of buttons, to give users better indication of what they do.
• The breadcrumb for the current page is not clickable, because a link is not needed for the user's current page.
• Horizontal scrolling within breadcrumbs container when the length of the breadcrumbs overflows the width of the page.
• Wrap the breadcrumbs in a nav component, to create a "navigation" landmark region on the page that's easy for screen reader users to find.
• All the breadcrumbs are inside of an ordered list, to show hierarchy.
• Using CircleIconButton for all buttons with an icon in them, for better accessibility and consistent look+feel with other buttons in immich.

Other changes include:

• Hiding "Edit tag" button on the root tags page

How Has This Been Tested?

• Navigate from the root of the tree all the way to leaves in both the /folders and /tags pages
• Use both the breadcrumbs and the "Go to parent" button to navigate up the tree
• Use the root directory button to get to the base folders/tags pages
