LibGfx+LibWeb: Add new Path class with Skia backend, use for 2D canvas This thing is essentially a wrapper around an SkPath, although we do some indirection via a PathImpl class to keep the door open for alternative rasterizer/path backends in the future. We also update the 2D canvas code, since that was the only code that used Painter+DeprecatedPath, and this allows us to just drop that code instead of temporarily supporting it until the next commit.

LibGfx+LibWeb: Add Path::glyph_run() and use in canvas Canvas text painting needs to support per-glyph font fallbacks, which means we can't hand over responsibility for text shaping to Skia and instead need to extract glyph paths from our own shaped GlyphRun.

LibWeb: Port painting to use the new Skia-backed Gfx::Path SVG and and CSS border rendering now sits on top of SkPath instead of the old Gfx::DeprecatedPath. Due to an imperceptible (255, 255, 255) vs (255, 254, 255) color diff in one ref test, I changed that test to not depend on border rendering for a positive result, since that was incidental.
