Redesign paused in debugger overlay (Android)

[huntie]

Summary

Context

Continued review of built-in dev UI controls for iPhone Duo / wider screen devices.

Android counterpart to #58950.

Notes

• The capsule, its popup, placement and animations move out of DefaultDevLoadingViewImplementation into DevBanner, an internal class it now owns. The paused overlay is a PausedDevBanner subclass that overrides its open members: window type, dimming, stack level, height, padding, the leading icon, the two-line text and the tap. The public API is unchanged.
• The paused banner never passes through setDevLoadingEnabled, so a paused app always says why it is not responding.
• The ic_resume PNGs are replaced with one vector pause icon, and the dialog's layout and backgrounds are dropped.

[Android][Changed] - Paused in debugger overlay: Redesign as a floating capsule

Test Plan

• ✅ On the Pixel 10a emulator (API 37), a paused message from a scripted DevTools session shows the banner over the dimmed app.
• ✅ While paused, a tap on the app content is swallowed, and the disconnected banner's dismiss button above it still takes the touch and dismisses it.
• ✅ With the disconnected banner shown, the paused banner stays on top and the disconnected banner sits 12dp below it.
