Description

WordPress 6.7 is going to contain the support for post formats in Query Block & Posts API ( see https://core.trac.wordpress.org/changeset/59115/ ).

Gutenberg currently has the gutenberg_add_format_query_vars_to_query_loop_block function which is backporting the same behaviour when run on WordPress < 6.7, but when run on WordPress 6.7 the gutenberg_add_format_query_vars_to_query_loop_block actually duplicates the taxonomy query in the WP_Query's query arguments produced by the build_query_vars_from_query_block function.

IMHO, we should not introduce the same taxonomy query in case it's already handled by WordPress itself.

Step-by-step reproduction instructions

1. Have WordPress 6.7 (beta) installed
2. Have Gutenberg 19.4.0 installed
3. run the build_query_vars_from_query_block with same params as used in the related PHPUnit tests ( see https://core.trac.wordpress.org/changeset/59115/ ) and observe the duplicate taxonomy query entry.
