## What is the bug

The endianness detection in `src/util_hash.c` produces a false result on macOS with GCC 13 or later. For whatever reason, [`#include <sys/param.h>`](https://gitlab.dkrz.de/icon-libraries/libfortran-support/-/blob/316d3dc6edb6ef0f4f1b9adaf9f3cb27a7bb831a/src/util_hash.c#L49) does not define the `__DARWIN_BYTE_ORDER` and `__DARWIN_LITTLE_ENDIAN` macros when [`#define _POSIX_C_SOURCE 200112L`](https://gitlab.dkrz.de/icon-libraries/libfortran-support/-/blob/316d3dc6edb6ef0f4f1b9adaf9f3cb27a7bb831a/src/util_hash.c#L45). And that leads to the wrong values of the `HASH_LITTLE_ENDIAN` and `HASH_BIG_ENDIAN` macros. See also https://gitlab.dkrz.de/icon/icon-mpim/-/merge_requests/684#note_300951

.

## How do you fix it

The endianness detection is delegated to CMake.

## What is the new feature
Support for single-precision as working-precision in libfortran-support. Related to icon-mpim MR (https://gitlab.dkrz.de/icon/icon-mpim/-/merge_requests/558), and libiconmath MR (libiconmath!13

).

## How is it implemented
- New CMake argument `FS_ENABLE_SINGLE_PRECISION`, disabled by default
- Precision handling: Introduction of `src/mo_iconlib_kind.f90` shared by fortran-support and iconmath:
  - Precision (dp+sp): Using iso_fortran_env variables `dp=>real64` and `sp=>real32`
  - Working precision (wp): `FS_ENABLE_SINGLE_PRECISION==TRUE` -> `wp=real32`, else `wp=real64`
  - Variable precision (vp): `FS_ENABLE_MIXED_PRECISION==TRUE` -> `vp=real32`, else `vp=wp`
- Extensions of some functions to include sp and dp interfaces
- Kind for `t_ptr` types is `wp` by default, with wp or dp or sp versions specified by suffix.

This removes an anti-pattern from `CMakeLists.txt` (I'm very sorry for introducing it). The most annoying part about it is that it makes it difficult for a parent project (e.g. ICON) to support multi-configuration backends properly. Basically, the only right place to set `CMAKE_BUILD_TYPE` is on the command line when calling `cmake` (and generating for a single-configuration backend). Also, see [here](https://stackoverflow.com/questions/24460486/cmake-build-type-is-not-being-used-in-cmakelists-txt/24470998#24470998

This updates the `add_icon_c_test` macro in `cmake/gtest_helper.cmake`:
1. The macro is turned into a function to avoid namespace pollution.
2. The function is renamed to `fs_add_c_test`.
3. The function now accepts named options `SOURCES` (followed by a list of source files of the test) and `ARGS` (followed by a list of command-line arguments for the test).
4. The old signature of the macro is still supported, i.e. it is possible to call something like `add_c_test(UtilHashTest ctest_util_hash.cpp)`, but it made sense to me to switch to the new one.
5. The `UtilFileTest` test is now provided with an extra command-line argument and it runs on `${CMAKE_CURRENT_BINARY_DIR}` instead of `.` as it was before !28.

String lists grow dynamically, removing the need for preallocated arrays. This simplifies
handling of large variable groups in the icon initialization phase.

The output lists of `add_to_list` are now `ALLOCATABLE`. They may be passed an unallocated
argument, which is treated like an empty list and allocated using the new `new_list`
subroutine. That subroutine initially allocates space for 8 strings. Every time the list
needs to grow, the allocated size doubles. This ensures constant amortized runtime for
adding to the list. No provisions are made for shrinking the list size, because they are
usually short-lived.

The tests for `add_to_list` are adapted for the new interface, checking list expansion.
A new test for `new_list` is added.
