The code relocation feature allows code and data section to be located
inside a designated RAM region.
Currently, this feature supports relocation of code (text) and data
including mutable data (data), read-only data (rodata), and
zero-initialized data (bss).
However, relocation of non-initialized data sections was not previously
supported, meaning that any data annotated with the __noinit attribute
could not be relocated into the desired RAM region.
This patch adds a NOINIT memory-type which can be used implicitly or
explictly in the zephyr_code_relocate() CMake function. This causes the
build system to generate additional linker-script section-matching rules.
By the nature of noinit data, no action is required by Zephyr at boot.
