Revert "Add a file to trivially disable tool building or testing"

This reverts commit ab018c76e14b87f3c9e0b7384cc9b02d94779cd5.

This also adds the `ToolBuild::is_ext_tool` field to replace the previous
`ToolBuild::expectation` field, to indicate whether a build-failure of
certain tool is essential.
