Android: Add possibility to provide app main lib name without metadata

Normally, the app's main library's name is read from a metadata field
in the AndroidManifest.xml file, which is filled out by
androiddeployqt.
Add a protected variable in QtLoader for the app main library name
that can be set to provide the library name without the metadata field.
This is useful in cases where we don't have a manifest file filled
by androiddeployqt, for example when embedding QML to an existing
Android app.
As a side effect, change the name of existing variable for the main
library and the method to access it to make it more explicit they refer
to the library's absolute path.
