Previously devtools used a nested workspace for its bazel configurations. This meant framework dependencies were consumed via npm.
Now devtools is part of the root bazel directory that all other files in this codebase fall under. This allows us to build devtools using local angular packages, removing the need to consume these dependencies with npn. This is useful because we no longer have to update these dependencies with an automated tool like renovate, and our CI tests will always run against the most up to date framework packages.
This commit runs tslint --fix with the angular/angular tslint configuration on the files inside the devtools codebase.
Notably, the file-header rule in `tslint.json` was missing a default attribute. This commit adds that default attribute and sets it to the
license header that is present in all files in this repo. After running tslint --fix with this default added, this commit added the license header to all files in the devtools directory. Note for the reviewer: the automatically added license headers were added as comments with the "/*!" prefix. Since we want these comments removed in builds, and the rest of the codebase uses "/**", a simple find and replace was performed on the devtools directory to change these prefixes to "/**".
Previously, camel case was used for bazel labels in the devtools directory. This commit changes these labels to snake case except in the case where the label is identical to the directory name that the BUILD file is in.
Formats the entire devtools directory with the ng-dev formatting tool. Previously we relied on prettier, so this commit also remove prettier from devtools' dependencies.
