Adds a `--wait-for-jsdebugger` CLI option which will spin the event loop until
the debugger connects to allow debugging _some_ startup code paths, such as the
beginning of the `browser.js` file.
Startup code paths that run before the DevTools CLI handler will be missed for
now. This can be improved in the future if we move this to an earlier phase of
app startup.

For simple rules like function spacing, we can auto-fix these across the code
base so they are followed in a consistent way.
To generate this patch, I ran:
./mach eslint devtools --no-ignore --fix
After this, I reverted any changes to third party files that we really do want
to ignore.

Move major DevTools files to new directories using the following steps:
hg mv browser/devtools devtools/client
hg mv toolkit/devtools/server devtools/server
hg mv toolkit/devtools devtools/shared
No other changes are made.
