Improved: Use ‘depends-on’ attribute instead of “component-load.xml” …

…(OFBIZ-11296)

We currently have two ways to define component loading order. Either
by using ‘depends-on’ attribute in “component-config.xml” or by adding
a “component-load.xml” file at the root of a component directory.

“depends-on” is more flexible because it handles partial ordering when
“component-load.xml” defines a total order which is not necessarily
meaningful, so it is better to rely only “depends-on”.

This removes the usage of “component-load.xml” to use ‘depends-on’
instead. The dependency declarations correspond to the total ordering
previously defined but will need to be refined in the future to relax
unnecessary dependency declarations.

Only “framework/base/config/component-load.xml” which defines the
top-level directories order (framework, applications, themes and
plugins) is kept.
