Guess the location of fidl-format

This change introduces two ways that the FIDL extension tries to find
fidl-format. Both of these techniques involve finding the root of the
Fuchsia repo by looking for the .fx-build-dir file.

* Try to walk up the directory hierarchy of each of the workspace
directories, checking if any contains .fx-build-dir.
* Try to find .fx-build-dir in all of the current workspace directories.

In each case, the extension uses the location in this file to construct
a likely path where fidl-format might exist.
