Rename constants to be unique (chrome/renderer)

When building using jumbo, files gets merged and
constants with the same name may end up in the
same namespace and conflict. This happens for:
chrome/renderer/chrome_content_renderer_client.cc
chrome/renderer/extensions/extension_hooks_delegate.cc
chrome/renderer/extensions/tabs_hooks_delegate.cc

This commit solves the issue by renaming the constants
to something more file specific.

Enable jumbo support in //chrome/renderer

Without jumbo, chrome/renderer takes around
7 CPU minutes, which is around 1.2 % of the
total build time.

This commit will enable jumbo support for
this target, reducing build time when using
jumbo.
