patch 9.2.0119: incorrect highlight initialization in win_init()

Problem:  When initializing a window in win_init(), w_hl is reset to
          NULL without ensuring existing highlight overrides are
          cleared (after v9.2.0113)
Solution: Clear highlight overrides and reset w_hl in win_init(). Remove
          the redundant VIM_CLEAR() from win_init_empty() (Foxe Chen).
