Fix theme selector resetting the buffer size (#25425)
Closes https://github.com/zed-industries/zed/issues/25413 As the issue points out well, themes do not need to alter any in-memory state on load: that is done via settings file load. Originally, it was introduced in https://github.com/zed-industries/zed/pull/4064 and https://github.com/zed-industries/zed/pull/24857 had restored that behavior, which seems wrong to do. Apart from removing that part, removes unnecessary methods and emphasizes that in-memory state is the Buffer/UI size — no need to add `Adjusted` there as the settings file presence is already enough. Release Notes: - Fixed theme selector resetting the buffer size
