Editor: Simplify usage of block_has_support() function by supporting a string.

Browse Source 
Most block feature checks are for a single feature string, and for such cases it is not intuitive to require an array for the `$feature` parameter of the `block_has_support()` function.

This changeset brings it in line with other functions like `post_type_supports()`, allowing to pass a string for the `$feature`. An array is still supported for more complex cases where support for sub-features needs to be determined. This change furthermore includes a very minor performance tweak by avoiding calls to the `_wp_array_get()` function if a single feature string is being checked for.

Fixes #58532.
