Add VMA flags into showmap report so that we can distinguish different
sections of an executable or a library.

Also fix bugs that made it not compile on host. Motivation is to be
able to analyze smaps files easily on the host.

Needed by showmap and also android_s_Debug to classify each allocation
into multiple heaps.
The APIs added are:
ForEachVmaFromFile - Global API to parse a file expected to be in the
same format as /proc/<pid>/smaps and make a callback for each VMA found.
ProcMemInfo::ForEachVma - Same as 'ForEachVmaFromFile' but for a
ProcMemInfo object corresponding to a process(pid).
ProcMemInfo::Smaps - Wrapper to ProcMemInfo::ForEachVma, except the
function collects 'struct Vma' in a member vector and returns the
reference for the same.
Added showmap2 using the APIs and the corresponding tests the same time.
