add SREBOT, SHARED, TSSBOT contents (fixup for #1223)

PR #1223 only staged the deletions of the old paths because the new
top-level directories were still untracked when the commit was authored.
This commit adds the actual restructured tree: SREBOT/ (existing bot),
SHARED/ (vromfs, data_parser, ICONS/MAPS/FONTS, DAGOR_FILES,
update_game_files), and TSSBOT/ (skeleton).
