gdb: Replace gdb::optional with std::optional

Since GDB now requires a C++17, we don't need the internally maintained
gdb::optional implementation.  This patch does the following replacing:
  - gdb::optonal -> std::optional
  - gdb::in_place -> std::in_place
  - #include "gdbsupport/gdb_optional.h" -> #include <optional>

This change has mostly been done automatically.  One exception is
gdbsupport/thread-pool which did not use the gdb:: prefix as it already
lives in the gdb namespace.
