When using direct isrs, a vector table is needed. However, if none is
present , i.e. `CONFIG_GEN_IRQ_VECTOR_TABLE=n`, this script failed. The
given error message was not helpful (`'NoneType' has no len()`).
This change makes it clearer, where to look for the problem.

When using the code and data relocation feature, every relocated symbol
would be marked with `KEEP()` in the generated linker script. Therefore,
if any input files contained unused code, then it wouldn't be discarded
by the linker, even when invoked with `--gc-sections`.
This can cause unexpected bloat, or other link-time issues stemming from
some symbols being discarded and others not.
On the other hand, this behavior has been present since the feature's
introduction, so it should remain default for the users who rely on it.
This patch introduces support for `zephyr_code_relocate(... NOKEEP)`.
This will suppress the generation of `KEEP()` statements for all symbols
in a particular library or set of files.
Much like `NOCOPY`, the `NOKEEP` flag is passed to `gen_relocate_app.py`
in string form. The script is now equipped to handle multiple such flags
when passed from CMake as a semicolon-separated list, like so:
"SRAM2:NOCOPY;NOKEEP:/path/to/file1.c;/path/to/file2.c"
Documentation and tests are updated here as well.

The current error messages are a bit cryptic, rework them to make them
more meaningful:
- add an extra message on the first error to explain what the errors
refer to.
- rework the error message to be more explicit.
- rework the priority string print to use a LEVEL+offset format to
somehow highlight that the number is the offset from the level, not
the actual priority.
- print the init function name in addition to the devicetree path.

Since bb590b5b6e introduced ordinals in the priority sequence, the "same
priority" case cannot happen anymore, furthermore the priority value in
the script is now the position of the function in the init sequence, so
if two devices have the same priority there's something real bad going
on.
Drop all the "same priority" handling code and tests, convert the case
into ane exception instead. Drop the init stubs as well from the test,
they are not required anymore.

Rework check_init_priorities to use the main executable file instead of
the individual object files for discovering the devices.
This should make the script more robust in case of stale files in the
build directory, and also makes it work with LTO object files.
Additionally, keep track of the detected init calls, and add a handy
"-i" option to produce a human readable print of the initcalls in the
call sequence, which can be useful for debugging initialization problems
due to odd SYS_INIT and DEVICE interactions.

This commit introduces all the necessary changes for
enabling the usage of shared interrupts.
This works by using a second interrupt table: _shared_sw_isr_table
which keeps track of all of the ISR/arg pairs sharing the same
interrupt line. Whenever a second ISR/arg pair is registered
on the same interrupt line using IRQ_CONNECT(), the entry in
_sw_isr_table will be overwriten by a
(shared_isr, _shared_sw_isr_table[irq]) pair. In turn, shared_isr()
will invoke all of the ISR/arg pairs registered on the same
interrupt line.
This feature only works statically, meaning you can only make use
of shared interrupts using IRQ_CONNECT(). Attempting to dynamically
register a ISR/arg pair will overwrite the hijacked _sw_isr_table
entry.

The syscall generation phase parses all header files to look
for potential syscalls, and emits all the relevant files to
enable syscalls. However, this results in all the syscall
marshalling functions being included in the final binary.
This is due to these functions being referred to inside
the dispatch list, resulting in ineffective garbage
collection during linking. Previous commits allows each
drivers and subsystems to specify which header files
containing syscalls are relevant. So this commit changes
the syscall generation to only include the syscalls needed
for the build in the syscall dispatch list and removing
various bits related to that. This allows the linker to
garbage collect unused syscall related function, and thus
reducing final binary size.
