Add BreakpadParser for symbolization of traces. Perfetto's trace_to_text tool supports adding symbols to Android traces by using llvm_symbolizer to extract symbols from the binary files. Support for windows was also recently added, but breakpad support is needed for official chrome builds. The BreakpadParser class was created to be able to obtain symbols to symbolize traces from multiple platforms. The class has a ParseFile method that parses a breakpad file and saves function names and their corresponding start addresses to the Symbol struct. Symbol objects are saved in a vector to be used in symbolization. Bug: b/191080142 Change-Id: I46b5760d7746868e7523c0185d853029862ede24
