Move gn secondary_source to the build/ directory

Move gn secondary_source to the build/ directory

It's a goodness to sequester build configuration in the build/
directory. The gn secondary_source stuff was under tools/gn for
historical reasons, so move it to a more appropriate place.

BUG=None
TEST=do a gn build of base_unittests, run said unittests.

I did the following to test:

$ gn gen out/Debug
$ ninja -C out/Debug base_unittests
$ ./out/Debug/base_unittests

Please let me know what else I should do to be sure this works!

Hm, tryserver failures with problems like:


ninja -C
/mnt/scratch0/b_used/build/slave/linux_chromium_gn/build/src/out/Release all
-j50
ninja: Entering directory
`/mnt/scratch0/b_used/build/slave/linux_chromium_gn/build/src/out/Release'
[1/1 | 0.000] Regenerating ninja files
ninja: error: '../../tools/gn/secondary/third_party/angle/angle_commit.h',
needed by 'gen/commit.h', missing and no known rule to make it


Which is kinda not surprising :-) is the bot not using the new .gn or something?
Is there something I need to do to make things start afresh with the new
secondary_source path?

In build/secondary/third_party/angle/BUILD.gn, update this line:
hardcoded_commit = [ "//tools/gn/secondary/third_party/angle/angle_commit.h" ]

I think that is probably the only case like this.
