Android: Use dots to distinguish java build steps

This CL in conjunction with https://crrev.com/c/2142163 allows us to
better distinguish java build steps.

Example:
Time by build-step type:
  10.1 s weighted time to generate 678 .mojom-shared.o files (5555.1 s elapsed time sum)
  11.9 s weighted time to generate 1 .resource_ids files (11.9 s elapsed time sum)
  13.3 s weighted time to generate 296 .bytecode-rewritten.jar files (407.3 s elapsed time sum)
  15.4 s weighted time to generate 311 .jetified.jar files (505.0 s elapsed time sum)
  17.6 s weighted time to generate 6141 .stamp files (3093.7 s elapsed time sum)
  21.3 s weighted time to generate 244 .javac.jar files (1588.1 s elapsed time sum)
  26.1 s weighted time to generate 160 .lint.stamp files (2545.7 s elapsed time sum)
  29.6 s weighted time to generate 162 .errorprone.stamp files (1592.9 s elapsed time sum)
  62.4 s weighted time to generate 319 .dex.jar files (1794.8 s elapsed time sum)
 146.9 s weighted time to generate 21403 .o files (244220.0 s elapsed time sum)
418.0 s weighted time (291862.9 s elapsed time sum, 698.2x parallelism)
