This fixes the behavior of
```c++
ABSL_RAW_LOG(INFO, "RAW INFO: %s%c%s", "Hello", 0, "World");
```
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.

Many compiler optimizations, even some in Asan, assume that size of
the object on the stack is fixed. Compiler takes into account the lifetime
of the stack object, but it does not expect that size of the object can
change.

This assumption allow to accesses when ever object is alive.

However, this assumption does not work well with custom poisoning
of objects by sanitizers. `Cord` may poison parts of the object
to improve a precision of the bug detection. But compiler still may
load from poisoned parts of the object, assuming it's alive.

So without the patch we can have `false-positive`, because
compiler reordered load from poisoned local before size-check.
https://github.com/llvm/llvm-project/issues/100639

Alternative is to make compiler optimization to know about
possibility of local object resize, but it's not worth of effort,
as it's needed only for sanitizers so far.

Another minor issue fixed with this patch is `false-negative`.
https://github.com/llvm/llvm-project/issues/100640
Asan drops instrumentation of memory accesses proven to be inbound
of local variable. However if we if we take into account `custom
poisoning` we will have to pessimize too often: any random function
call can potentially `resize` a variable by `poisoning`.

We are already using similar `poisoning` workaround in libc++:

The correct CMake policy is set, but there is no option to switch the msvc runtime when configuring the project.

Since MSVC is a multiconfiguration build tool, we need to set this CMake variable internal to the project to ensure that all of the supported build configurations get properly set (i.e. `Release` builds use `/MT` or `/MD` and `Debug` builds use `/MTd` or `/MDd`).
I tried to explictly set these flags (i.e. -DCMAKE_CXX_FLAGS_XXX) when configuring the project, but these flags were being overwritten due to [explicitly setting compiler flags](https://github.com/abseil/abseil-cpp/blob/master/CMake/AbseilHelpers.cmake#L285).

Using abseil via CMake ExternalProject, for each compilation abseil is reconfigured. This leads to a new options-pinned.h generated and then a new options.h installed. Because of that new options.h file, all projects depending on abseil recompile entirely.

Using file(GENERATE ...) instead of file(WRITE ...) allows generating options-pinned.h only when the content is new or changed.

When depending on a compiled abseil code, abseil libraries cannot find each other even if they are all located in the same directory.

One fix is to edit the LD_LIBRARY_PATH, but it is not always that simple in a development environment.

Another way is to add the current location into the RPATH so all libraries can find each other. CMake provides simple command to control this at project scale.
