Now that -Wc++2a-compat is no longer enabled (bug 1887580), we don't need these pragmas disabling -Wc++2a-compat warnings about u8"" string literals' type changing from const char[] in C++17 to const char8_t[] in C++20.

Remove some type-level indirections from template-metaprogramming
helpers.
Additionally, replace some nearby uses of `typedef` with `using`, as
suggested by clang-tidy.
No functional changes.

When compiled with -std=c++17, u8"" string literals have type `const char[]`. When compiled with -std=c++20, u8"" string literals have type `const char8_t[]`. This patch adds the minimum char8_t overloads needed to compile Firefox with -std=c++20. If we want to use char8_t in more code or replace `Utf8Unit` with char8_t, that will require an extensive redesign of MFBT's and xpcom's string classes after we update from -std=c++17 to c++20.

The built-in version is better as it also allows annotating particular
parameters (it not only applies to method declarations).

This prevents it from being used in the foot-gunny way described in
comment 0.
This in turn allows us to add a constructor for temporary callables.
Turns out we only had test usages of non-temporary FunctionRefs, so this
is much simpler than the initial approach I considered.
Fix the tests to keep compiling, and add a test for the new constructor.

size_t is already correctly used in many places, only ConstIterator uses
uint32_t for position tracking. It would be better to align these data types
and use size_t everywhere.

MozTaggedMemoryIsSupported doesn't work under ASAN because it tries to prctl the
nullptr page. It should be harmless to simply call prctl and ignore the error.

Remove all of the code in `RefPtr` and `AgileReference` that allowed
for implicitly converting between the two in via constructors or the
assignment operator.
Replace these with a slightly-less-convenient-but-substantially-more-
explicit `Resolve` function family.
(This also eliminates the dependency that `class RefPtr` had on
`class AgileReference`.)

In the fx codebase, we tend to use __attribute__((naked)) for plain
assembly functions with a C interface. Instrumenting these functions can
mess up this assembly, so we conservatively also want to prevent
instrumentation.

The patch implements the move assigment operator in terms of the move
constructor. This fulfills the requirements for std::swap to compile.
