This patch add an example and pyhton base modules:
1.add memdump.py is an example to analyze memory
usage by python script.
2.add The most basic data structure analysis, like list, etc.
future ideas:
Maybe we can add modules related to "sched, drivers, arch, fs.." to
automatically analyze scripts to debug some problems

This PR is a modification that optimizes priority inheritance
for only one holder. After the above modifications are completed,
the mutex lock->unlock process that supports priority inheritance
can be optimized by 200 cycles.
Before modify: 2000 cycle
After modify: 1742 cycle

This commit aims to provide a way to get the current applied defconfig on runtime by providing CONFIG_BASE_DEFCONFIG that is updated when the configure and build scripts are run.
The "CONFIG_APPS_DIR" generated in .config has double quotes and is not recognized as a path by most make systems. This commits removes these double quotes to make the compile successfully.
The offset of the relevant registers in xcp will change after
enabling the FPU, this PR will add fpu offset correct the register offset

Currently when we modify some Kconfig related to some chip or
some architecture we need to run refresh.sh to all boards that
is too slow (more than one hour to finish).
This patch modify the script to update only the boards configs
of an specific chip or only the boards of an specific architecture.
Examples:
$ ./tools/refresh.sh --silent --defaults arch:renesas
Normalize us7032evb1/ostest
Normalize us7032evb1/nsh
Normalize skp16c26/ostest
Normalize rx65n-rsk2mb/netnsh
Normalize rx65n-rsk2mb/ipv6
Normalize rx65n-rsk2mb/nsh
Normalize rx65n-rsk1mb/netnsh
Normalize rx65n-rsk1mb/nsh
Normalize rx65n-grrose/netnsh
Normalize rx65n-grrose/ipv6
Normalize rx65n-grrose/nsh
Normalize rx65n/nsh
It updates the boards from all 'renesas' architecture (m9c, rx65n, sh1)
$ ./tools/refresh.sh --silent --defaults chip:rx65n
Normalize rx65n-rsk2mb/netnsh
Normalize rx65n-rsk2mb/ipv6
Normalize rx65n-rsk2mb/nsh
Normalize rx65n-rsk1mb/netnsh
Normalize rx65n-rsk1mb/nsh
Normalize rx65n-grrose/netnsh
Normalize rx65n-grrose/ipv6
Normalize rx65n-grrose/nsh
Normalize rx65n/nsh
It updates all the boards from renesas chip 'rx65n' family
The syntax check of kconfiglib is stricter than kconfig-frontends,
but the warnings of kconfiglib are not catched by Makefile. Since kconfiglib
is implemented by python, the return value of the shell is always zero($?),
In this PR, I redirected the relevant standard errors to the file to check
whether the kconfig warning is occurred

Current Toolchain.defs set the compile flags directly, it's OK for
target specified gcc toolchain.
But some LLVM based toolchains (Rust/Zig etc) use single toolchain to handle all supported paltform.
In this patch, arch level Toolchain.defs export standard LLVM style arch flags, and let <Lang>.defs to map them into internal style,
This will simplify the intergration of non-c language.

Some targets, such as qemu-rv support multiple architectures. The required flags need to passed to the linker when built "out-of-tree" in the application directory.
Initially supporting ESP32-C3 chip, to be followed by other RISC-V-based
chips from Espressif.
