chore(codersdk/toolsdk): improve static analyzability of toolsdk.Tools (#17562)

* Refactors toolsdk.Tools to remove opaque `map[string]any` argument in
favour of typed args structs.
* Refactors toolsdk.Tools to remove opaque passing of dependencies via
`context.Context` in favour of a tool dependencies struct.
* Adds panic recovery and clean context middleware to all tools.
* Adds `GenericTool` implementation to allow keeping `toolsdk.All` with
uniform type signature while maintaining type information in handlers.
* Adds stricter checks to `patchWorkspaceAgentAppStatus` handler.
