refactor(ivy): Implement computeStaticStyling (#34418)

Browse Source 
The `computeStaticStyling` will be used for computing static styling value during `firstCreatePass`.

The function takes into account static styling from the template as well as from the host bindings. The host bindings need to be merged in front of the template so that they have the correct priority.

PR Closes #34418
