Fixed an issue in `libcxx/utils/gdb/libcxx/printers.py`.

With gdb 17 (binutils 2_44) pretty-printers do not work anymore because calls to `gdb.printing` requires `import gdb.printing` statement, which was missing from the `printers.py`.

Broken after commit [binutils-gdb/fc14343205d3a68db1fc139e4af9796be208fab4](https://github.com/bminor/binutils-gdb/commit/fc14343205d3a68db1fc139e4af9796be208fab4), and `import gdb.printing` was first referenced in [binutils-gdb/ee06c79b0fefd5e4ed5e7a1171dc3440130e41da](https://github.com/bminor/binutils-gdb/commit/ee06c79b0fefd5e4ed5e7a1171dc3440130e41da)
