refactor(ivy): migrate all host-specific styling instructions to element-level styling instructions (#30336)

This patch removes all host-specific styling instructions in favor of
using element-level instructions instead. Because of the previous
patches that made sure `select(n)` worked between styling calls, all
host level instructions are not needed anymore. This patch changes each
of those instruction calls to use any of the `elementStyling*`,
`elementStyle*` and `elementClass*` styling instructions instead.
