Remove unused load statements from .bzl files

After transitive loads have been disabled in Blaze, unused load statements have
no effect (besides not useful memory consumption).

The CL has been created automatically by calling `buildifier --lint=fix --warnings=load` on all .bzl files.

The following additional command were run on all affected files to clean them up:

  * buildifier -a -v --lint=fix --warnings=load-on-top
    Moves all load statements to the top of a file
  * buildifier -a -v --lint=fix --warnings=same-origin-load
    Compresses all load statements from the same .bzl file to one load statement
