build system: explicitly disable LTO plugin to reduce the number of simultaneously open files
Closes IDF-923 and IDFGH-1764

* use Environment::Exit() to avoid PS process hanging
* old-fashioned exceptions
* try-catch-finally necessary
* disable Windows Defender Task when Defender module not installed
* cleanup script checks Defender module existence too
* fixed uninstall of Start Menu LNK
* use Command Prompt instead of Command Line wording
+ Desktop shortcut
* iterate through PSMODULEPATH when looking for WD module

... to reduce the number of simultaneously open files at link time.
When plugin support is enabled in the linker, BFD's (and the
corresponding file handles) are cached for the plugin to use. This
results in quite a large number of simultaneously open files, which
hits the default limit on macOS (256 files).
Since we aren't using LTO now, disable it explicitly when invoking the
linker.

add support of modbus master ascii
rename base dir name of master and slave example to be mb_slave, mb_master to avoid conflict with sdio/slave example test
add Kconfig option to enable ASCII and RTU mode separately
update ASCII options + remove cast for errors
added baudrate for examples into Kconfig
updated magic numbers for timer timeout
put ascii private definitions into one file
we should only load one module once.
if we load one module twice, python will regard the same object loaded in the first time and second time as different objects.
it will lead to strange errors like `isinstance(object, type_of_this_object)` return False
If we have multiple configs, we need to flash DUT with different binaries. But if we don't close DUT before apply new config, the old DUT will be reused, so new config name will not be applied.
Currently we use config and test function as filter when assign cases to one CI job. It's not necessary as the runner can run test with different configs / test functions. Now we will try to assign as many cases to a job as possible, to reduce the amount of jobs required.
This commit adds a pair of scripts, find_apps.py and build_apps.py.
These scripts are intended to be used in various CI jobs, building
multiple applications with different configurations and targets.
The first script, find_apps.py, is used to prepare the list of builds:
1. It finds apps for the given build system.
2. For each app, it finds configurations (sdkconfig files) which need
to be built.
3. It filters out the apps and configurations which are not compatible
with the given target.
4. It outputs the list of builds into stdout or a file. Currently the
format is a list of lines, each line a JSON string. In the future,
the tool can be updated to output YAML files.
The lists of builds can be concatenated and processed with standard
command line tools, like sed.
The second script, build_apps.py, executes the builds from the list.
It can execute a subset of builds based on --parallel-count and
--parallel-index arguments.
These two scripts are intended to replace build_examples_make,
build_examples_cmake, and the custom unit-test-app logic (in the
Makefile and idf_ext.py).

Write COMPONENT_KCONFIGS_SOURCE_FILE and
COMPONENT_KCONFIGS_PROJBUILD_SOURCE_FILE files always even when
COMPONENT_KCONFIGS or COMPONENT_KCONFIGS_PROJBUILD are empty variables
because kconfiglib expects them to exist.
This allows the processes launched from idf_tools.py to use the value
of IDF_PATH. One such example is the installation of Python packages,
when requirements.txt uses IDF_PATH to refer to the esp-windows-curses
package.

It gave us a better performance of RSA operations. (2~11 times)
The old modexp implementation (Z = X ^ Y mod M) loaded all the data into
the hw registers and was waiting for completion, but due to
the hardware RSA implementation, the calculations always started with 4096 bit,
which took a lot of time.
Measurement results (measurements were made for keys: 2048, 3072 and 4096 bits)
(Old) - Sliding-window exponentiation (HAC 14.85):
keysize = 2048 bits
RSA key operation (performance): public [93206 us], private [280189 us]
keysize = 3072 bits
RSA key operation (performance): public [293614 us], private [858157 us]
keysize = 4096 bits
RSA key operation (performance): public [653192 us], private [1912126 us]
Instead (Old) - Sliding-window exponentiation (HAC 14.85) was implemented
(New) - Montgomery exponentiation (HAC 14.94) which showed
better performance on private and public keys.
keysize = 2048 bits
RSA key operation (performance): public [14504 us], private [149456 us]
keysize = 3072 bits
RSA key operation (performance): public [35073 us], private [392743 us]
keysize = 4096 bits
RSA key operation (performance): public [58650 us], private [787186 us]
For this reason, the old implementation was removed
and the MBEDTLS_HARDWARE_MPI option was turned on by default.
Why the MPI_INTERRUPT option is removed:
the old implementation used calculations on the hardware and
it took a lot of time (10ms - 500ms). And in order not to stand idle
while waiting for completion, an interrupt option was added.
This made it possible to carry out other tasks during the calculation,
and this one to block. The new method is free from such a drawback and
the maximum duration of one RSA HW operation does not exceed 70us (usually 2-70 μs).
This option is no longer needed.

Use rev-parse to get the HEAD directory instead of manually looking for
it. This method works in the main repository, worktrees and submodules.
