[micro-frontend]: --sap* variables conflicts

[nnaydenow]

Background

If ui5-webcomponents are used in micro-frontend scenario --sap* variables conflicts. Currently the used variables are defined by the latest registered runtime by the time of the registration, not by version which leads to broken components in following scenario: We have 1 main application and 1 widget where both are using ui5-webcomponents. Main application is the first registered runtime and it's using version 1.18.0. The widget is the second registered runtime and it's using version 1.15.0.

Expected Behaviour

--sap* variables from version 1.18.0 to be used.

Description

Investigate possible solution of how we can decide which variables to be loaded.
