ART may extract dex files into memory from zip files.
This CL supports getting symbols from extracted dex files in below steps:
1. Change map names in "/dev/ashmem/dalvik-xxx extracted in memory
from yyy.apk" format into yyy.apk!/xxx format.
2. Support dumping dex files in yyy.apk!/xxx format in JITDebugReader.
3. Support reading symbols from dex files in yyy.apk!/xxx format
in DexFileDso.
Also refactor FileHelper to return android::base::unique_fd,
refactor ArchiveHelper to wrap all operations to zip files.

Test: run simpleperf_unit_test.
Test: run simpleperf on an app containing extracted dex files.

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.
