QQuickSvgParser: respect end iterator when skipping whitespace

The code contained a number of while loops to eat all whitespace or
parse all digits without respecting the end-sentinel. An input string
ending with whitespace or digit results in a possibly unterminated
out-of-bounds read.

To fix this in parsePathDataFast, remove the special handling of
whitespace in this code, and instead just continue the outer loop if the
current character is whitespace.

Pass the end sentinel to the parseNumbersArray and toDouble helpers so
that we can consistently test whether incrementing the str point has
reached the end.

Add test coverage, both to the QML svgpath test case, and to the
QQuickPath test using the private parsePathDataFast API directly. The
input data is the same in both cases. Note that running these tests
without the fix might only fail in an ASAN-enabled build.
