simpleperf: reduce load time of the report generated by report_html.py.
1. Add TimeLog class to measure load time.
2. In SampleTableView, add table contents gradually at idle time.
3. In FlameGraphViewList, draw 10 flamegraphs at a time and add a "more"
button for the rest. It first draw the skeleton of the flamegraphs,
then draw the details at idle time.
4. In FlameGraphView, first add all svg contents to a string array, then
add the string array to the svgDiv. This is much faster than adding
contents directly to the svgDiv.
When tested with a perf.data generated by system wide recording, the
load time is reduced from almost endless (2s for SampleTableView, others
for FlameGraphViewList) to about 1s.
Also fix a small error in report_html.py and clean up cdn links.
