conandeps: replace kind/level columns with a "via" shortest-path column

Browse source 
Show how each indirect dependency is reached ("libfoo -> libbar") instead
of a bare hop count, "-" for direct dependencies, and "(+N)" when other
packages also require it directly. Rows sort direct-first then by path so
a branch's transitive dependencies stay together.

the same colour coding.
Reading the table: rows are sorted with direct dependencies first
(alphabetically), then indirect ones by increasing level of indirection. The
`level` column is the number of hops from your conanfile: 1 is direct, 2 is
required by a direct dependency, 3 by one of those, and so on (shortest path
counts). The HTML report has the same column.
Reading the table: the `via` column is the shortest path from your conanfile
to the package – `-` for a direct dependency, `MyDepB` for something MyDepB
requires, `MyDepB -> Zigma` for something Zigma requires, and so on. `(+N)`
means N other packages also require it directly (boost above is pulled in by
both MyDepA and Zigma); the dependency hierarchy section shows every path.
Rows are sorted direct-first, then by path, so a branch's transitive
dependencies stay together.
