Remove scopeguard from platform

• Component: Platform
• Status: RESOLVED FIXED

[Christopher Reid]

FileSystem uses scopeguard so filesystem can't be moved into PAL while scopeguard is in WebCore.

Patch - Fixing a poorly merged line

I'm surprised so few places use this.

Regardless, there's nothing "Platform" about this class - It belongs in WTF

[Sam Weinig]

WTF already has ScopeExit, which looks similar. Maybe we can just remove ScopeGuard.

Is there a reason this needs to be std::function?  We're trying to use WTF::Function instead because it's non-copyable.

For some reason I thought ScopeGuard was using std::function, but I was mistaken. I'll change it to WTF::Function.
