Explicitly enable /INCREMENTAL linking for gyp-generated Debug builds.

Explicitly disable it (/INCREMENTAL:NO) for Release, and for the
following targets that require it:
  chrome.dll
  interactive_ui_tests.exe
  perf_tests.exe
  unit_tests.exe

Explicitly specificy /SUBSYSTEM:CONSOLE as default for linking,
and match current practice by overriding with /SUBSYSTEM:WINDOWS for:
  chrome.exe
  chrome.dll
  media_player.exe
  sandbox_poc.exe

TEST=none
BUG=none
