 The process of generating a class for a style variation is not checking
 for spaces.

 **Step-by-step reproduction instructions**

 Add a style variation such as (note the spacing in the name):

 {{{#!php
 <?php
 register_block_style( $block, array(
         'label'                         => esc_html__( 'Style Name',
 'slug' ),
         'name'                          => 'style-class-1 style-class-2'
 ) );

 }}}

 When this style variation is selected by the user the CSS class attached
 to the block is
 {{{
 is-style-class-1 style-class-2
 }}}


 ''register_block_style'' function should return an error it doesn't
 contain spaces.
