Fix breakpoint mixins for custom breakpoint maps (#25264)

When using the `media-breakpoint-between` or `media-breakpoint-only`
mixins with a custom breakpoint map – not defined as `$grid-breakpoints`
– the mixin incorrectly defaults back to the global `$grid-breakpoints`
map in certain situations. This commit correctly passes on the
`$breakpoints` argument to the other mixins called within the block.
