Only SolidBrush types are created, remove other brushes.
We only ever create a CFDE_SolidBrush, there is nothing which creates Texture, Hatch or LinearGradient brushes. This Cl removes all the code that isn't used for SolidBrush. A followup Cl will rename SolidBrush to Brush and remove the Brush interface in favour of the concrete class. BUG=pdfium:468 Review URL: https://codereview.chromium.org/1877383002
