Add width and height html attr in img tag

[Utwo]

Whenever we have width and height in pixels set in styles on element node, add the values to the width and height attributes in image tag without unit.

Hey @Utwo, to implement this we have to add attributes here https://github.com/teleporthq/teleport-code-generators/blob/development/packages/teleport-uidl-resolver/src/html-mapping.ts#L21, and anywhere else we have to work?

Hey @chavda-bhavik this is kind of core thing, needs little more changes and primarily some investigation of the best way to handle. I got your invitation for fixing #545 issue. I will set things for you there :)
