[Blazor] Rename EnvironmentBoundary component to EnvironmentView

[Copilot]

Renames the newly added EnvironmentBoundary component to EnvironmentView per API review decision. The component renders child content conditionally based on the current hosting environment, analogous to MVC's <environment> tag helper.

Description

• Renamed EnvironmentBoundary → EnvironmentView in Microsoft.AspNetCore.Components.Web
• Updated PublicAPI.Unshipped.txt to reflect the new type name
• Renamed unit test file and updated all nameof/type references
• Renamed E2E test file and updated all references
• Renamed EnvironmentBoundaryContainer.razor → EnvironmentViewContainer.razor and updated component tags
• Updated Index.razor dropdown entry to reference EnvironmentViewContainer

Usage:

<EnvironmentView Include="Development">
    <p>Debug mode enabled</p>
</EnvironmentView>

<EnvironmentView Exclude="Production">
    <p>@DateTime.Now</p>
</EnvironmentView>

src/Components/test/testassets/BasicTestApp/EnvironmentViewContainer.razor:5

• The container still uses the old DOM id environment-boundary-test, which no longer matches the renamed component/container and makes the E2E test selectors misleading. Consider renaming this id to environment-view-test and updating the corresponding By.Id(...) lookups in the E2E test.
  src/Components/test/E2ETest/Tests/EnvironmentViewTest.cs:27
• Later in this test, the element lookup still uses the old id environment-boundary-test. Since this test is being updated for the EnvironmentView rename, consider also renaming that id to something like environment-view-test (and updating the BasicTestApp container markup) to keep identifiers consistent and easier to search/debug.
