Most of the changes relating to cxx23 are due to the fact that
`unique_ptr` now requires to see the full definition of T, if the
deleter is required to be defined in the header, which means that a lot
of cases where forward declaration was possible now require the full
type definition.

[build] Set use_cxx23 to true by default (new features not allowed yet!)
C++23 is NOT allowed in chromium yet. This just starts compiling the
code with c++23. Embedders of //build can still opt out for now
by overriding the variable in .gn.
