Fix support for building with CEF 5060

[WizardCM]

Description

Add a couple version checks for logging added in recent hotfixes to ensure continued compilation on the previously supported version of CEF.

Fixes #480

Motivation and Context

Generally, we aim to support the currently shipping CEF version and the previous (in this case 5060) to ensure easy verification of new issues with a current codebase (that is, easy downgrading for comparison), or to be able to easily revert in case of major bugs.

CefGetExitCode() did not exist until 124, and additional parameters were added to OnRenderProcessTerminated.

How Has This Been Tested?

Toggle between CEF versions on Windows. Both compiled.

I would almost rather we just ifdef the entire function signature instead of parts of it, but this is probably fine. I'll think about it.

On second examination, we already do this elsewhere, so it's probably fine.
