For CONFIG_USERSPACE the input from gen_app_partitions.py there is
a need to be able to specify input files as well as input sections
patterns for zephyr_linker_section_configure(). This is used for
app partitions from libraries (which generate input patterns like
foo.a:*(.data*)).
This adds documentation to zephyr_linker_section_configure() to clarify
what INPUT allows, and also adds some parsing tricks to ld_script.cmake
to properly add the file patterns when they are missing.

It seems as if ld_script.cmake hasnt handled
zephyr_linker_section_configure( ALIGN ...) due to a typo
in a variable name,

As Zephyr currently requires CMake version 3.20.0, update all
occurrences of cmake_minimum_required.

Scripts generated with ld_script.cmake also need to have the _align
symbols defined so that they work with TLS values.

Fixes: #41435
The use of %<symbol>% works well in Linux and MacOS but when passed
to the linker script generator in Windows the %<symbol>% is processed
by the windows shell causing the value to disappear and thus an empty
value inside the generated ld linker script or scatter file.
This is fixed by using the @ character instead of the % character.

The root cause of #38591 was region symbols being placed before the
section description for data region.
Some region start symbols are placed before section description, other
region start symbols are placed inside the first section in the region
and thus identical to the sections own first symbol.
To support both schemes with the linker generator, a new
`SYMBOL SECTION` argument has been added to the zephyr_linker_group()
function.
The ld_script.cmake linker script generator has been updated to support
the new argument so that generated ld linker script has identical
behavior to the templated ld linker scripts.

Adding intial version of ld_script.cmake.
This script can generate ld linker script from the Zephyr CMake linker
functions.
This script is called by the build system and all linker settings, such
as memory regions, groups, output sections, linker symbols defined with
Zephyr CMake linker functions are passed to this script in order to
generate an ld linker script.
