Remove lib-remoteconfig HTTP module

Delete the lib-remoteconfig HTTP subsystem and its embedded static content. Removed files include HTML/JS/CSS content headers (lib-remoteconfig/http/content/*), HTTP headers and utilities (lib-remoteconfig/include/http* and httpd), and corresponding implementation sources and JSON handlers (lib-remoteconfig/src/http* and src/json/*). This cleans up the remoteconfig HTTP implementation and its generated/packed assets.
