LaCrOS: Replace defined(OS_CHROMEOS) with BUILDFLAG(IS_ASH)

The change is mostly mechanical replacing defined(OS_CHROMEOS) with BUILDFLAG(IS_ASH) and GN variable is_chromeos with is_ash. Only the insertion of "//build:chromeos_buildflags" into appropriate deps in BUILD.gn is done semi-manualy. The change should not change the behaviour of any build.

This is in preparation to switching lacros build from target_os=linux to target_os=chromeos so that lacros does not include any additional code due the switch.

Please note that any new defined(OS_CHROMEOS) and is_chromeos introduced to should be consistent with the new meaning.

Please refer to this short document http://go/lacros-replace-chromeos-macro-with-ash for full context.
