gdbsupport: Let construct_inferior_arguments take gdb::array_view param
Adapt the construct_inferior_arguments function to
take a gdb::array_view<char * const> parameter instead
of a char * array and an int indicating the length
and adapt the only call site.
This will allow calling it more simply in a follow-up
patch introducing more uses of the function.
gdbsupport/ChangeLog:
* common-inferior.cc, common-inferior.h (construct_inferior_arguments):
Adapt to take a gdb::array_view<char * const> parameter.
Adapt call site.
