Simpleperf: Add SPLIT and SPLIT_END records to handle big records.
Previously we split KernelSymbolRecord because it is > 65535. Then
I found TracingDataRecord can also be > 65535. So it is better to
handle big records when reading and writing perf.data.
record_file_writer.cpp splits a big record into multiple SPLIT
records followed by a SPLIT_END record, and record_file_reader.cpp
restores the big record when reading SPLIT and SPLIT_END records.
Also Add RecordHeader to represent record having size > 65535.

Simpleperf: adjust default mmap_pages for system wide profiling.
System wide profiling have much more records to pass between kernel
and simpleperf, thus it needs a larger buffer than process profiling.

simpleperf: support event group.
Kernel supports monitoring several events as a group, so they are
scheduled on and out at the same time. Add --group option to
stat command and record command.
Adjust the method to calculate miss rate in stat command: limit
the matched events in the same group or with scale == 1.0.
