refactor(turbo-tasks): Codemod/migrate all ResolvedVc casting callsites to use the new synchronous APIs

[bgw]

This is a follow-up to #75055.

After #75055, the async methods are just facades around the synchronous versions, to avoid breaking the API.

I made this PR using:

sg run -p 'ResolvedVc::try_sidecast::<$$$TY>($$$ARGS).await?' -r 'ResolvedVc::try_sidecast_sync::<$$$TY>($$$ARGS)' -U
sg run -p 'ResolvedVc::try_sidecast($$$ARGS).await?' -r 'ResolvedVc::try_sidecast_sync($$$ARGS)' -U
sg run -p 'ResolvedVc::try_downcast::<$$$TY>($$$ARGS).await?' -r 'ResolvedVc::try_downcast_sync::<$$$TY>($$$ARGS)' -U
sg run -p 'ResolvedVc::try_downcast($$$ARGS).await?' -r 'ResolvedVc::try_downcast_sync($$$ARGS)' -U
sg run -p 'ResolvedVc::try_downcast_type::<$$$TY>($$$ARGS).await?' -r 'ResolvedVc::try_downcast_type_sync::<$$$TY>($$$ARGS)' -U
sg run -p 'ResolvedVc::try_downcast_type($$$ARGS).await?' -r 'ResolvedVc::try_downcast_type_sync($$$ARGS)' -U

Delete the implementation of the non-sync methods, and then:

sg run -p 'ResolvedVc::try_sidecast_sync' -r 'ResolvedVc::try_sidecast' -U
sg run -p 'ResolvedVc::try_downcast_sync' -r 'ResolvedVc::try_downcast' -U
sg run -p 'ResolvedVc::try_downcast_type_sync' -r 'ResolvedVc::try_downcast_type' -U

Then rename the methods implementations in resolved.rs to match.
