The version.cmake file should be the sole file used from the cmakev1
build system. There's no need to maintain the IDF_VERSION information in
two separate locations.

Helper for obtaining the default value of a variable. It returns the
value of the specified variable based on the following order of
precedence, with the highest precedence first:
1. Environmental variable
2. CMake cache variable
3. Provided default value
This can be used to retrieve the value of variables that might also be
set in the environment or cache, such as PYTHON or SDKCONFIG.

With the default signature of `cmake_parse_arguments`, without using
`PARSE_ARGV`, it's not possible to determine if options were not
specified or set as an empty string (or empty list)[1]. If an empty
string is passed to the `PATHS` option, the variable parsed by
`cmake_parse_arguments` is not defined. This issue can be addressed by
using `PARSE_ARGV`, but this approach only works for functions and
requires CMake version 3.31 or newer. Additionally, when `PARSE_ARGV` is
used for multiple value option, the values are not concatenated into a
single list, which is inconvenient, as the lists are instead escaped. If
the `PATHS` option is not defined, set it to an empty string. This
allows passing an empty string, as well as a mix of lists and
individual strings, through PATHS.
The behaviour can be seen with a simple example:
$ cmake -P test.cmake
```test.cmake
cmake_minimum_required(VERSION 3.22)
function(test)
set(options)
set(one_value)
set(multi_value PATHS)
cmake_parse_arguments(ARG "${options}" "${one_value}" "${multi_value}" ${ARGN})
#cmake_parse_arguments(PARSE_ARGV 0 ARG "${options}" "${one_value}" "${multi_value}")
message("PATHS: ${ARG_PATHS}")
endfunction()
test(PATHS "one;two;three" "four" "five;six" "seven")
```
```
PATHS: one;two;three;four;five;six;seven
vs
PATHS: one\;two\;three;four;five\;six;seven
```
Also update the current usage of __get_absolute_paths, as the check for
empty PATHS is no longer necessary.

This is a basic CMake project that currently includes tests for
displaying build and component properties, as well as testing component
priority. These tests should be removed once proper CI testing is
in place.

Discover component directories and initialize components within them.
This process does not include managed components, which should be added
separately at a later stage. To facilitate this, some minimal
functionalities are introduced, such as build properties, component
properties, and other helper functions.
