main: split start_boot_splash up into two functions

Right now start_boot_splash loads the theme, then
shows it.

It's going to be useful in the future to preload the
theme, so this commit breaks the two operations out
into two functions, load_theme and show_theme,
and makes start_boot_splash just call those two
functions.
