Extract media components into standalone Microsoft.AspNetCore.Components.Media package.

Description

Moves Image, Video, FileDownload, MediaSource, MediaContext, and MediaComponentBase out of Microsoft.AspNetCore.Components.Web into their own package as discussed in #63540.

Namespace change: Microsoft.AspNetCore.Components.Web.Media → Microsoft.AspNetCore.Components.Media

New package structure:

• src/Components/Media/src/ — library targeting Microsoft.AspNetCore.Components + Microsoft.JSInterop (no Web dependency)
• src/Components/Media/test/ — unit tests (all 14 pass)

What was removed from Microsoft.AspNetCore.Components.Web:

• Web/src/Media/ directory (6 source files)
• Web/test/Media/ directory (2 test files)
• All Web.Media.* entries from PublicAPI.Unshipped.txt

Infrastructure:

• Registered in eng/ProjectReferences.props
• Added to AspNetCore.slnx, Components.slnf, ComponentsNoDeps.slnf
• InternalsVisibleTo added for test project in Microsoft.AspNetCore.Components.csproj
• BasicTestApp updated to reference new package and namespace

// Before
@using Microsoft.AspNetCore.Components.Web.Media

// After
@using Microsoft.AspNetCore.Components.Media

Pull request overview

This PR extracts the Blazor media component suite (Image, Video, FileDownload, plus supporting types) out of Microsoft.AspNetCore.Components.Web into a new standalone Microsoft.AspNetCore.Components.Media package, including a namespace move from Microsoft.AspNetCore.Components.Web.Media to Microsoft.AspNetCore.Components.Media.

Changes:

• Introduces a new src/Components/Media/ library + test project, with corresponding PublicAPI files.
• Updates test assets (BasicTestApp) and unit tests to reference the new package/namespace.
• Wires the new projects into repo infrastructure (project reference providers and solution/solution-filter inclusion) and updates Components.Web’s unshipped API list to reflect the move.
