Renaming "modlib" to "libelf" is more in line with the implementation content,
which makes it easier for individual developers to understand the capabilities of this module.

1. fix https://github.com/apache/nuttx/issues/14774.
Change the defconfig of libcxxtest and select libcxxabi by default to
fix sim:libcxxtest build in macOS CI can't find cxxabi.h.
2. fix https://github.com/apache/nuttx/issues/15491.
libcxxabi cannot be used with uclibc, so when compiling macos sim, libcxxabi cannot be selected by default in Kconfig.

Summary:
- Unified the specification of LLVM architecture and ABI types across the CMake and Makefile configurations.
- Introduced `LLVM_ARCHTYPE` and `LLVM_CPUTYPE` variables in the CMake configuration to match the Makefile's approach.
- Standardized the ABI type (`LLVM_ABITYPE`) to `sysv` for both Linux and macOS host configurations.
Impact:
- Ensures consistent LLVM target definitions across build systems (CMake and Makefile).
- Simplifies future maintenance by avoiding divergence in LLVM-related configurations.
- No functional changes to the build output; only the internal representation of LLVM target information is aligned.

config-testing-heap is changed to conofig-testing-heap, so the citest tools need to change.
Signed-off-by: tengshuangshuang <tengshuangshuang@xiaomi.com>
Under apps/testing folder, the macro of CONFIG_TESTING_MM is changed to CONFIG_TESTING_HEAP.
So we need to update the defconfig containing CONFIG_TESTING_HEAP in the nuttx/boards folder.

add sim_rpmsg_port_uart.c to verify the rpmsg port uart wrapper layer,
The physical transport layer could be:
1. SIM_RAM_UART(current)
2. SIM_UART(through "socat" virtual "/dev/pts/*", "socat" could monitor the bus data)

This commit cleans up redundant header file includes throughout the codebase.
The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.

2. fix the error when modify the sim_rpmsg_virtio to port to
rpsmg_virtio_lite;

Because rpmsg_virtio_lite is a better name to inform user that the
rpmsg virtio (original name) is a lite implementation of rpmsg virtio.

After compilation, when starting nsh, the following crash occurs.
==2500151==Shadow memory range interleaves with an existing memory mapping. ASan cannot proceed correctly. ABORTING.
==2500151==ASan shadow was supposed to be located in the [0x1ffff000-0x3fffffff] range.
==2500151==Process memory map follows:
0x30000000-0x33dd4000 /nuttx/nuttx
To avoid overlaps, change the starting address of the text segment.
Using Ttext-segment=0x30000000 causes a crash when starting the 32-bit SIM.
Using -Ttext-segment=0x50000000 causes a crash when starting the 64-bit SIM.
Setting -Ttext-segment=0x40000000 resolves all issues perfectly.

1. Excerpted from: https://github.com/ARM-software/LLVM-embedded-toolchain-for-Arm/blob/main/samples/src/cpp-baremetal-semihosting-prof/proflib.c
2. Since llvm profile supports more than just gcov, and some features have not yet been explored, two clang gcov implementations are supported after this patch
3. Using this lib only supports the gcov compilation options of "-fprofile-instr-generate -fcoverage-mapping"
4. This file is heavily dependent on the compiler clang version, and is currently aligned with ci, supporting 17.0.1 and below. 18 and above are not supported by this library due to different internal implementations of the compiler

The reason for removing math.h is that undefining __GLIBC__ does not take effect. By default, sim will use the toolchain's math library and undef __GLIBC__ in the source file.

use the dynamic library .so of the binding compilation environment,
and then modify the dynamic loader of elf at runtime to run sim elf across system versions
1.add post-build for sim build
2.collect dynamic .so and dynamic interpreter
3.add execution script for the entire package sim elf
change text-segment to 0x50000000
because patchelf will modify the .dynamic section in elf,
the upward alignment of elf will be less than 0x3fffffff,
which will cause asan shadow memory overlap error
