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.

This commit introduces armlink steering file.
A steering file in armlink allows Zephyr to keep using existing linker
symbols defined in ld scripts and used throughout the code tree.
The steering file is generated at build time in order to resolve Zephyr
linker symbols to their corresponding armlink symbols.
As example, Zephyr defines __ramfunc_start which corresponds to the
armlink auto defined Image$$ramfunc$$Base symbol.
Or __init_PRE_KERNEL_1_start which corresponds to Image$$init_0$$Base.

This is the initial support for the armclang compiler together with the
armlink linker.
Introduced in this commit:
- armclang compiler support
- armlink linker support
- armlink scatter file generator for scatter loading
- dual pass linker script generation
