CI: Bump CEF/Chromium from 4638 (95) to 5060 (103)

[WizardCM]

Description

This updates the browser dependency used by obs-browser from Chromium 95 to Chromium 103. This is the last Chromium version that supports the particular texture sharing we use, so we may be stuck here a while - not sure yet.

This update includes:

• Texture sharing patches for macOS and Windows
• Jim's legendary texture fix on Windows
• Audio monitoring support

This update removes/excludes (due to limited time & added complexity):

• MediaHandler API

obsproject/cef@4204d54

Motivation and Context

Ideally we want Chromium to be as up to date as possible, to ensure a bug free experience for users.

• Fixes Visuals Stop Rendering When Source is Repeatedly Refreshed obs-browser#356

It's worth noting that we don't actually know why the above linked bug is fixed in this version. It was definitely still broken in Chromium 102, and nothing was specifically done to alleviate the issue.

Many thanks to @pkviet on adapting patches for each Chromium version and building across all platforms.

How Has This Been Tested?

• Loaded chrome://version, chrome://gpu, YouTube and some WebGL demos in browser sources
• Loaded various webpages in browser docks

Note: Windows x86 has been tested via CI. macOS Intel over CI seems to hang on shutdown?
