Add kPrintWithPostScriptType42Fonts feature.
Add an off by default base::Feature for controlling whether PostScript
printing generates Type 42 fonts on Windows. This will speed up printing
for some printers that support PostScript level 3 and have a TrueType
rasterizer. Since this feature is experimental, having a base::Feature
toggle will allow the feature to be rolled out in a controlled manner.
This CL includes:
- Plumbing for the browser to tell the PdfToEmfConverter service to use
the new printing mode.
- New Printing.ConversionSize metrics to see how the new printing modes
perform size-wise.
- A very basic sanity test.
- Control for the feature in chrome://flags.
- Control for the feature via an enterprise policy.
Also fix another Windows-only printing enterprise policy to use
"MS_WIN_NAME" when referring to Windows.
