662d7f11d5 Fixes to support building in -std=c++20 mode.
* Structs with user-declared constructors are no longer considered
  aggregates, so remove the declarations when possible
* Types of both arguments to "==" must match to avoid "ambiguous
  function call" warning
* Various types of math involving enums are deprecated, so replace with
  constexprs where necessary
* ABSL_CONST_INIT must be used on definition as well as declaration
* volatile memory may no longer be read from and written to by the same
  operator, so replace e.g. "n++" with "n = n + 1"
* Replace an outdated check for no_unique_address support with
  __has_cpp_attribute
* std::result_of(f(x)) has been removed, replace with
  std::invoke_result(f, x)

This is a reland of f5e261aaf65cdf2eb903cdf40d651846be44f447

This CL disables RTC_NO_UNIQUE_ADDRESS on MSan builds since
there have been some issues.

f5e261aaf6 Introduce RTC_NO_UNIQUE_ADDRESS.
This macro introduces the possibility to suggest the compiler that a
data member doesn't need an address different from other non static
data members.

The usage of a macro is to maintain portability since at the moment
the attribute [[no_unique_address]] is only supported by clang
with at least -std=c++11 but it should be supported by all the
compilers starting from C++20.
