Stop using sources_assignment_filters in chrome/browser/ui/BUILD.gn

set_sources_assignment_filter() causes files to be magically excluded
from sources lists based on path substrings. It is considered a
mis-feature of gn, see bug.

Convert BUILD.gn to use conditionals to include source files only on
the platform where they are used.
