Extract all colors from the stylesheets, reduce their number by merging the similar ones and organize them into themes represented by CSS variables.

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.
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.
