core: kern.ld.S: move .scattered_array* into .data.rel.ro

Moves the symbols tagged with .scattered_array* from the .rodata output
section into a new output section: .data.rel.ro, which is also writeable
(hence the suppression of __SECTION_FLAGS_RODATA in scattered_array.h)
but placed in tee.elf to be mapped read-only after relocations are
applied. The new section is created only when core ASLR is enabled,
otherwise no relocation can occur and we can keep the previous code.

core: rename KEEP_INIT() and KEEP_PAGER()

The KEEP_INIT() and KEEP_PAGER() macros are quite often used in C files
immediately after the definition of a function or a structure without a
blank line in between. This style mimics what the Linux kernel does for
a similar use cases: EXPORT_SYMBOL().

Unfortunately, the checkpatch.pl tool expects a blank line after
structure and function definitions, except for a few special cases such
as EXPORT_SYMBOL(). As a result we often get unwanted warnings when we
use KEEP_INIT() and KEEP_PAGER(). Among the exceptions are all words
starting with DECLARE_ or DEFINE_, so by renaming our macros we could
avoid the checkpatch warnings.

This commit renames KEEP_INIT() and KEEP_PAGER() to DECLARE_KEEP_INIT()
and DECLARE_KEEP_PAGER(), respectively. The assembler macros are also
renamed for consistency. No functional change is expected.

core: add scattered array

Adds a scattered array which allows defining arrays scattered over
several source files. The implementation is based on some support by the
linker.

This is a generic solution to initcalls and other similar scattered
initializations.
