Add support for multi resolution icons

To support HiDPI we need a way to load two copies of icons, a low resolution version and a high resolution version.

To support this, this change does the following:
  - split theme_resource.grd into three files:
      - theme_resources.grd: icons that only have one resolution
      - theme_resources_standard.grd: low resolution icons
      - theme_resources_large.grd: high resolution icons
   - theme_resource.grd and theme_resources_standard.grd and compiled into chrome.pak/chrome.rc for all platforms.
   - theme_resources_large.grd is compiled into theme_resources_large.pak for platforms that want high resolution icons (currently only Mac)
   - gfx::Image now support icons with multiple resolution

Currently not all ThemeService APIs return multi-resolution images. Once this is checked in I'll work on converting them as I go.

Note, this change will have to be coordinated with the change to reorganize theme resources. I'll work with saintlou on that.

BUG=75812
TEST=Added a TIFF to theme_resources.grd. Verified that the toolbar icon had a mutliresolution image. Verified that unit tests passed.
