Split components_tests into a separate gyp file

Split components_tests into a separate gyp file

This enables us to depend on components from shell, since
components_tests already depends on shell.

Diff upload seems to have failed, can you try again?

Which components are you planning to use from content shell? I wonder if it
should then eventually move out of //content since it's a little dirty to have
stuff under //content depend on //components.

Cheers,

I want to use breakpad from content shell.

content shell is technically a content embedder, and as such it's not too dirty
:)

LGTM

I agree that using components from content shell is not dirty in the conceptual
sense since as you say it is an embedder. It's just slightly confusing in that
this embedder lives within the //content folder, which in general is not allowed
to depend on //components.
