build-aux: Update Flatpak CEF from 103/5060 to 127/6533

[tytan652]

Description

Flatpak counterpart of #11213

Reminder that obsproject/obs-browser#450 (or an alternative) is required to avoid the shutdown crash with browser docks.

The CEF module is also modified to:

• Use the pre-built wrapper included in the tarball
• Preserve debug symbols inside its binaries
  • The copy done later by OBS Studio build-system will be split from its debug symbols

Motivation and Context

Update CEF on the Flatpak and preserve CEF debug symbols which will be put in the .Debug Flatpak extension.

How Has This Been Tested?

Build with CEF and debug symbols are generated and compressed.

Tested on x11 (i3 wm), via flatpak artifact without problems. Also, Custom Browser Docks Window are behaving normal

Looking great on macOS (Sonoma) 14.6.1. Virtual camera has stopped working, but browser sources are all perfect. Tested recent Chromium features by using CSS mask-image to mask areas of the page with an local SVG <mask>. Flawless! Thank you so much for this update.

As a note, this PR only updates the Flatpak version. PR #11213 updates Windows and macOS.
