[a11y] TableView select-all checkbox aria-label is hardcoded to "Select All" and not customizable

[zinap-ensemble]

Provide a general summary of the issue here

In TableView, when used with selectionMode="multiple" selectionStyle="checkbox", the aria-label of the select-all checkbox is hardcoded to "Select All" with no way to override it. When multiple TableViews appear on one page, every select-all checkbox announces identically, so screen reader users can't tell them apart.

🤔 Expected Behavior?

There should be a way to customize the aria-label of the select-all checkbox — e.g. a selectAllLabel prop on TableView, or a fallback that composes the table's own aria-label (e.g. "Select all Event Providers") — so screen reader users can distinguish between select-all checkboxes when multiple tables appear on one page.

😯 Current Behavior

When a page renders multiple TableViews with selectionMode="multiple" selectionStyle="checkbox", every select-all checkbox announces identically as "Select All" — even though each table has its own distinguishing aria-label. Fails WCAG 3.3.2 (Labels or Instructions).

💁 Possible Solution

Default the aria-label of the select-all checkbox to one built from the table's own aria-label (e.g. "Select all " + the table's aria-label), and also expose a way to customize it directly — e.g. a selectAllLabel prop on TableView (and/or Table in react-aria-components) — to override that default when needed.

🔦 Context

We have a page with multiple TableViews rendered side by side (one per data group), each with selectionMode="multiple" selectionStyle="checkbox". An accessibility audit flagged that screen reader users can't distinguish between the "Select All" checkboxes across these tables since they share an identical, non-descriptive aria-label.

🖥️ Steps to Reproduce

Render two TableViews with selectionMode="multiple" selectionStyle="checkbox" on the same page, each with a distinct aria-label. Inspect the select-all checkbox in each table — both have aria-label="Select All".
