This commit adds support for bold text in DxRenderer. For now, bold fonts are always rendered using DWRITE_FONT_WEIGHT_BOLD regardless of the base weight. As yet, this behavior is unconfigurable. References Previous refactoring PRs: #9096 (DxFontRenderData) #9201 (DxFontInfo) SGR support tracking issue: #6879 Closes #109
