New filter for header image tag attributes

[junaidbhura]

There is currently no way to filter the attributes of the header image tag before it is used to build the header image tag HTML in the get_header_image_tag() function.

I've attached a diff to solve this problem by adding a new 'get_header_image_tag_attributes' filter.

I'm not sure a filter is really needed here since the function accepts an array of attributes that override any defaults. Am I missing something?

The idea is to have this work similar to wp_get_attachment_image_attributes . There is currently no way to modify the header image's attributes like a normal attachment image.

There is a get_header_image_tag filter, but that is applied after the image's HTML has already been built.
