target/hexagon: Rename macros.inc -> macros.h.inc

Since commits 139c1837db ("meson: rename included C source files
to .c.inc") and 0979ed017f ("meson: rename .inc.h files to .h.inc"),
EMU standard procedure for included header files is to use *.h.inc.

Besides, since commit 6a0057aa22 ("docs/devel: make a statement
about includes") this is documented in the Coding Style:

  If you do use template header files they should be named with
  the ``.c.inc`` or ``.h.inc`` suffix to make it clear they are
  being included for expansion.

Therefore rename "macros.inc" as "macros.h.inc".
