SVGPathParser: Move unaltered emits to a separate code-path

SVGPathParser: Move unaltered emits to a separate code-path

Hoist the check for normalized parsing/normalization out of the emit*
methods, and with it the non-normalized emittal out of emit*. This type
of emittal is trivial, so the use of SVGPathParser::m_mode can be
avoided altogther in this code-path.
This leaves the emit* methods with only doing normalized emittals, and
SVGPathParser::m_pathParsingMode only needs to be checked in the main
parsing method, so it becomes possible to just use the parameter
directly.

This CL moves SVGPathParser into (one of a couple) of intermediate states in
preparation for the new consumer-side interface (read: these switches will
disappear again later one, but this hopefully makes for easier reviews...)
