This PR adds a templateLock attribute to columns and group. When this attribute is set the locking of the blocks is set to the attribute value instead of relying on the inherited value.

This allows the locking of these blocks to be controlled by templates, patterns, etc.

supersedes: #25869

How has this been tested?

I verified now locking is not inherited by using sample cpt templates, and sample blocks with inner block templates.

I verified I could control the locking of the group block by using the templateLock attribute.
By pasting the following code on the code editor I verified that the first group block is not locked, while the second group block is locked.

<!-- wp:group -->
<div class="wp-block-group"><div class="wp-block-group__inner-container"><!-- wp:quote -->
<blockquote class="wp-block-quote"><p></p></blockquote>
<!-- /wp:quote --></div></div>
<!-- /wp:group -->

<!-- wp:group {"templateLock":"all"} -->
<div class="wp-block-group"><div class="wp-block-group__inner-container"><!-- wp:quote -->
<blockquote class="wp-block-quote"><p></p></blockquote>
<!-- /wp:quote --></div></div>
<!-- /wp:group -->

I verified I could control the locking of a column by pasting the following code on the code editor I verified column 1 is locked while the second column is not.

<!-- wp:columns -->
<div class="wp-block-columns"><!-- wp:column {"templateLock":"all"} -->
<div class="wp-block-column"><!-- wp:paragraph -->
<p>1</p>
<!-- /wp:paragraph --></div>
<!-- /wp:column -->

<!-- wp:column -->
<div class="wp-block-column"><!-- wp:paragraph -->
<p>2</p>
<!-- /wp:paragraph --></div>
<!-- /wp:column --></div>
<!-- /wp:columns -->
