Eliminate pen style and history stream parameter smuggling

- Introduce struct text_pen bundling (fg, bg, sl) across screen and core
- Reduce text_append from 9 to 7 parameters
- Reduce text_commit from 8 to 6 parameters
- Reduce hist_runs_add_pen from 5 to 3 parameters
- Reduce sc_text_ascii and sc_ascii_fast from 6 to 4 parameters
- Remove unused fg, bg parameters from mark_row_blank
- Introduce struct hist_stream_state in src/hist.c, reducing stream_lines from 9 to 5 params and lf_rows from 10 to 6 params
- Introduce struct hist_view_pos in src/hist_view.h, reducing term_hist_view_row_pos from 9 to 7 params
