simpleperf: support showing symbols for interpreted java code.
To convert from a dex_pc (returned by libunwindstack) to a symbol name,
we need below things:
1. The mapping info of the vdex file containing the dex_pc.
2. The offsets of dex files in the vdex file.
So make below changes:
1. Record none executable maps when profiling java code.
2. Refactor dso code to add a new type for dex file, using DexFileDso
to store dex file offsets in a vdex file, and load symbols from that
vdex file.
3. Add read_dex_file.cpp to read java symbols using libdexfile.
4. Change the format of file section in record_file_format.h, to store
dex file offsets in vdex files.

Bug: http://b/77236599
Test: Run simpleperf to profile several apps manually, can see
Test: callstacks of both java code and native code.
Test: Run simpleperf_unit_test.
