Allow disabling the BPA part of bidi reordering
* src/xdisp.c (syms_of_xdisp): New variable 'bidi-inhibit-bpa'.
* src/bidi.c (bidi_paired_bracket_type): If 'bidi-inhibit-bpa'
is non-nil, return BIDI_BRACKET_NONE for all characters.
* lisp/frame.el: Add 'bidi-inhibit-bpa' to the list of
variables whose changes require redisplay. (Bug#38407)
