VMManager: Log power profile and GPUs on startup

[F0bes]

Description of Changes

• Implements power profile logging on Windows
• Implements logging GPUs on Windows and Linux*
• Implements distro logging on Linux (Instead of just 'Linux')

*There are some limitations on driver version logging on Linux. It should always work for the dGPU (which is really what matters most).

Rationale behind Changes

Improves the ability to provide support when you can see if the user has set a poor power profile, or if their drivers are outdated.

Suggested Testing Steps

Run PCSX2 and look at the console.

Linux example

Windows example (Sorry, two screenshots, and the driver version is now aligned like Linux)

For windows, you'd be better off enumerating the devices in the registry. IIRC enumerating adapters can bring dual GPU setups out of sleep, which would delay startup by several seconds. Same with invoking nvidia-smi or whatever on Linux.

An alternative approach that I've suggested in the past, would be to have a "generate support report" type button/menu, which dumps all this information, as well as configuration etc, to a file. Doesn't matter if that takes several seconds to run.

I was worried about the same thing. This all runs on the CPU thread though so it shouldn't be an issue if you're using PCSX2 via the UI (by the time you pick a game it should be ready). Maybe I can put this into its own temporary thread? There might be the issue of something else using the console while it's running though, I haven't checked.

If this is the desired approach, I will remove the GPU portion of the this PR. I don't really want to get into UI work.

I also need to fix pulling the build string from /etc/os-release apparently it's up to the distro if they want to use quotes or not. Can't have anything fully standardized on Linux.

Works great.

You could just comment it out/surround with #if 0, that way it can be used for the support log generation later on.
