This change adds a new macro, ABSL_HARDENING_ASSERT_SLOW, which can be used for hardening assertions which have too great a performance impact to enable widely.  It also adds an additional supported value for ABSL_OPTION_HARDENED to only enable assertions which are not slow.  ABSL_OPTION_HARDENED=1 will continue to enable all hardening assertions, while ABSL_OPTION_HARDENED=2 will only enable assertions not marked as SLOW.

We enable this validation when sanitizers are enabled rather than in debug mode because debug mode can be enabled/disabled separately in different translation units, which can cause bugs for this type of validation. E.g. a hashtable that was moved from in a TU with debug enabled is then destroyed in a TU with debug disabled.

When targeting Android NDK r25 (reached EOL now, but still in some use) one gets the following error:
```
$(SOURCE_ROOT)/contrib/restricted/abseil-cpp/absl/time/time.h:1762:37: error: invalid operands to binary expression ('std::strong_ordering' and 'const std::strong_ordering')
  if (auto c = lhs_hi <=> rhs_hi; c != std::strong_ordering::equal) {
```

The error indicates the lack of `operator<=>` between two `std::strong_ordering` items.
I believe that this should be controlled by `__cpp_lib_three_way_comparison` (_Three-way comparison (library support)_, see [this article](https://en.cppreference.com/w/cpp/feature_test)), not by `__cpp_impl_three_way_comparison` (which stands for _Three-way comparison (compiler support)_).

Fixes #1725.
The problem was introduced in a2766235.

which would previously truncate at the `\0`. The new behavior is consistent with `printf`.

The GetTID() now uses the value of the current thread handle from
zx_thread_self() on Fuchsia for the thread ID. This is better than the default
implementation which uses pthread_self(), since that results in a 64-bit
pointer being truncated into the 32-bit pid_t type.

Since #1707 and #1710, `-Xarch_` option groups are present as single elements in the libraries' COPTS, and a `SHELL:` prefix is added to each of them. While these addressed certain build issues, they broke the handling of `-Xarch_` option groups in pkgconfig files.

Fix that by taking care of the `SHELL:` prefix in COPTS when generating pkgconfig files. The skip-next-flag mechanism is also removed as the option groups are now present as single elements.

An `operator->` that doesn't return a record type doesn't really serve a useful
purpose, and it is not required by the iterator concepts. I haven't been able
to find any usage in non-test code, so I'm removing it.

Even though the `pointer` type alias is now not being used anywhere, I'm keeping
it because otherwise some standard libraries don't accept `CharIterator` when
passed to `std::string::apend()`, for example.

We already have `swap(raw_hash_set&, raw_hash_set&)` thus we may expect argument dependent lookup will use that function in following code snippet:
```
absl::flat_hash_map<...> x, y;
using std::swap;
swap(x, y);
```
But in practice `std::swap` will be called because `swap(raw_hash_set&, raw_hash_set&)` requires derived-to-base conversion while `std::swap` doesn't (it is a function template), thus `std::swap` is picked by compiler.

To avoid this, we need a `swap` implementations which accept the exact `*_hash_*` types which is more preferred over `std::swap`.

Note that this will fix issues#1571.
