Functions to fetch pre-pinned Perfetto prebuilts.
This function is used in different places:
- Into the //tools/{trace_processor, traceconv} scripts, which are just plain
wrappers around executables.
- Into the //tools/{heap_profiler, record_android_trace} scripts, which contain
some other hand-written python code.
The manifest argument looks as follows:
