[check] Check includes using <bracket> style as well as "quotes"

This teaches the gn check tool to consider include directives using the
system <bracket> style in addition to those using the "quote" style.
The handling of the two is identical except that when examining a
system style include the directory of the file containing the include
is not implicitly considered an include directory.

This behavior is disabled by default and can be enabled in three ways:

1.) Set the variable 'check_system_includes' to true in a build's .gn
configuration file.
2.) Pass the '--system' flag to the 'gn check' command
3.) Pass the '=system' value to the '--check' switch for gen:
  gn gen --check=system
