Update how custom svg dimesions are applied

[gabriel-glo]

Description of the Change

• Update how custom svg dimesions are applied for get_image_tag and wp_get_attachment_image functions
• Separate the logic for defining custom dimensions in a set_svg_dimension function

Closes #6

How to test the Change

In any template output the image markup either by using get_image_tag or wp_get_attachment_image functions. Set the custom image size to either one of the registered image size names or a custom one via array [$width, $height]. Output should match the set dimensions.

Changelog Entry

This breaks behavior in wp_get_attachment_image(): before: any thumbnail size will inherit SVG width, height attributes now: only 'full' thumbnail will inherit SVG width, height attributes
