This further fixes problems when having a VIM extension (at least vscodevim)
enabled, by not calling `overrideCommand('type', commands.onEnter.handle)` when
enableEnhancedTyping is set to `false`.
The problem is dependent on the order in which extensions are activated, if
rust-analyzer is activated before `vscodevim`, rust-analyzer will register the
`type` command, and when `vscodevim` finally attempts to activate, it will fail
to register the command. This causes `vscodevim` to stop working properly.
This setting allows users to disable the registerCommand `type` in
rust-analyzer, allowing `vscodevim` to work. The setting defaults to `true`.
Currently changing the setting requires reloading of the window.
