Since SF3, inline definitions are first class citizen. I noticed that the GraphvizDumper does not inspect them. Here is the fix.

Same as #29103 but for 3.4.

This PR dump inline services using the call-stack to sort the code for instantiating them.
This makes easier to follow and matches the behavior one would expect (and has when using `ContainerBuiler` directly to create services.)

Some attributes being used in the phpunit configuration files, namely
failOnRisky and failOnWarning were introduced in phpunit 5.2.0. The
Composer configuration shows that tests should run with old versions of
phpunit, but phpunit only validates the configuration against the XSD
since phpunit 7.2.0.
These changes can be tested as follows:

wget http://schema.phpunit.de/5.2/phpunit.xsd
xargs xmllint --schema phpunit.xsd  1>/dev/null
find src -name phpunit.xml.dist| xargs xmllint --schema phpunit.xsd  1>/dev/null
