Update inputs files in WarpX (#4103)

Due to the recent changes in amrex::ParmParse, we must use the line
continuation character '\' for values spanning multiple lines. For Parser
expression, we could either double quotes to enclose the whole string or use
`\` as line continuation.

The old style multi-line values were removed in AMReX to avoid mistakes like

    algo.current_deposition = direct

    # galilean
    psatd.use_default_v_galilean  # Forgot = 1

Here, `psatd.use_default_v_galilean` is silently ignored because with the
old style multi-line support it becomes part of the values for the previous
definition (i.e., `algo.current_deposition = direct
psatd.use_default_v_galilean`). This case will now abort.
