    [gdb/build] Fix cli/cli-style.c build error with C++20

    PR build/34514 reports for a C++20 build:
    ...
    cli/cli-style.c:457:37: error: conversion from âconst char8_t [8]â to \
      non-scalar type âstd::stringâ {aka
âstd::__cxx11::basic_string<char>â} \
      requested
      457 | static std::string warning_prefix = u8"\u26A0\uFE0F ";
          |                                     ^~~~~~~~~~~~~~~~~
    ...

    The u8 literal is char[] until C++20, but char8_t[] since C++20.

    Fix this by using a reinterpret_cast<const char *>.

    Tested by rebuilding using GCC 15.3.0, with and without -std=c++20.
