gutenberg_add_global_styles_for_blocks should add all global styles.

[zpericic]

Closes #52276
Regression after #50310

What?

Load all elements global styles for non 'core/' blocks.

Why?

Any style with $metadata['path'] will be skipped if does not have element starting with 'core/'. We should use 'wp_add_inline_style' for all global styles.

How?

Call 'wp_add_inline_style' for all block global styles.

Testing Instructions

1. Install custom block (name in block.json not starting with "core/") with support any global style defined in styles.blocks.some/block.elements (eg. button, link, h[1-6]) of theme.json
2. Change some value for button, link, h[1-6] in styles.blocks.some/block.elements
3. See change are effective
