Add two new fake editor commands: Formatting and OrganizeImports, which delegate to textDocument/formatting and textDocument/codeAction respectively. Use this in simple regtests, as well as on save. Implementing this required fixing a broken assumption about text edits in the editor: previously these edits were incrementally mutating the buffer, but the correct implementation should simultaneously mutate the buffer (i.e., all positions in an edit set refer to the starting buffer state). This never mattered before because we were only operating on one edit at a time.
