[🚀uip-preview] make able to pass resizable attribute feature from snippet level

[ala-n]

As a UIP consumer, I want to be able to use both resizable/non-resizable examples in bounds of single UIP instance.

Proposed to add resizable as a feature of snippet

<script type="text/html"
              label="Some Example"
              uip-snippet
              uip-snippet-resiable>

The resizable attribute of uip-preview can be hadeled using any of mentioned options (@yadamskaya correct me if you prefer one):

• A. Simply remove and do not support on element level
• B. Support and use with priority
  JS is not necessary required for that option: just use marker value for that property in case it was set via snippet
  E.g. <uip-preview resizable> - always resizable, ignores snippet
  <uip-preview resizable="snippet"> - dynamically set by UIP code from snippet in case resizable was not presented with different value but passed as an option of snippet (will be removed if the next snippet is not resizable)

Note: please make sure in case resizable option was removed the inline size of preview area is flushed (as right now we will have a dynamic behaviour under resizable attribute)
