simpleperf: support profiling jited java code.
1. For each jit symfile, generate a Mmap2Record with a special flag
PROT_JIT_SYMFILE_MAP.
2. Call ReadMmapEventData() before dumping jit Mmap2Records, to keep
the order of samples and mmap records.
3. Handle finding symbols from maps with PROT_JIT_SYMFILE_MAP flags.
4. Pass PROT_JIT_SYMFILE_MAP flag to libunwindstack, to unwind
through jited methods.
Bug: http://b/73127105
Test: run simpleperf manually.
Test: run simpleperf_unit_test.
