[TF2] Allow self inspection
Description
This PR adds the Client tf_inspect_allow_self CVar, which defaults to 0, and the inspect_self Command.
When tf_inspect_allow_self is set to 1 and you attempt to inspect without looking at another player, you will instead inspect your equipped items as if you were inspecting another player, this is useful for custom gamemodes like VScript / SM VSH that often modify the attributes of your weapons, of which provide no simple or intuitive way to view them.
Executing inspect_self will always inspect yourself, good for those who wish to bind a key to inspect yourself while keeping the previous functionality of the inspect key.
This PR also allows you to close the inspect panel with +attack2 and +attack3, to more easily close the inspect panel when tf_inspect_allow_self is set to 1, just like it already does with +attack.
How does this affect MvM? Inspecting without target opens your upgrade menu.
Replying to https://github.com/ValveSoftware/source-sdk-2013/pull/1324#issuecomment-2932959089
tf_inspect_allow_self has no effect over inspecting in MvM and the inspect_self command will inspect your own upgrades as expected.
