[refactor] Allow `undefined` for UI location columns. Currently the devtools-frontend doesn't really distinguish between UI locations that point to the first column (represented as column number 0) and UI locations that refer to the whole line, and somehow we managed to get away with this mixed state. But for the language plugins to really provide a consistent stepping / breakpoint experience we need to preserve the information of whether a location refers to the whole line or to the first column. The communication to the language plugin continues to pass numbers for backwards compatibility, using `-1` to state the absence of column information (i.e. indicating that the location refers to the line as a whole).

DevTools frontend is also available on NPM as the chrome-devtools-frontend package. It's not currently available via CJS or ES modules, so consuming this package in other tools may require some effort.
The version number of the npm package (e.g. 1.0.373466) refers to the Chromium commit position of latest frontend git commit. It's incremented with every Chromium commit, however the package is updated roughly daily.
