Refactor InlineTextBoxPainter to avoid using CompositionUnderline
CompositionUnderline is a class that exists mainly so callers can specify the
information necessary for creating CompositionMarkers (start/end offset,
underline color, thickness, background color). It's currently also serving
double-duty in InlineTextBoxPainter to pass this information around after it's
retrieved from a CompositionMarker. With the introduction of painting support
for ActiveSuggestionMarker in https://codereview.chromium.org/2925543003, this
starts to seem kind of strange, if it didn't already (since we're creating
CompositionUnderlines from non-Composition markers). This CL refactors
InlineTextBoxPainter to pass around references to DocumentMarkers/
StyleableMarkers directly instead of creating CompositionUnderlines.
