build: Track all syscall deps

[mark-inderhees]

When working on #96892 I noticed that in some places cmake is only tracking syscall deps for those under ${ZEPHYR_BASE}/include when in reality syscalls can come from a number of places including those defined by users.

This PR updates cmake dependencies to track all inputs used in syscall generation.

I was able to verify the issue by creating an external zephyr module driver. Repo steps are somewhat complicated, as mentioned in #96892 and #96881, git is funny and will do full file delete/adds when modifying a few lines.

Repo

Part A: Setup external module

1. git clone https://github.com/mark-inderhees/zephyr-module
2. Stage changes to the driver syscall, save this patch as module.patch

3. Apply patch with git apply module.patch
4. Cache those changes

cp include/hello_driver.h /tmp/hello_driver.h
cp src/hello_driver.c /tmp/hello_driver.c

5. Revert state with

git restore include/hello_driver.h
git restore src/hello_driver.c

Part B: Setup repo

1. Clone my fork of blinky to use my test module, based of zephyr main

git clone https://github.com/mark-inderhees/zephyr-module
git checkout test-module-broke

2. Stage patch to use the updated syscall, save this patch as zephyr.patch

diff --git a/samples/basic/blinky/src/main.c b/samples/basic/blinky/src/main.c
index 263592497ef..870ff487026 100644

        if (ret != 0) {
                LOG_ERR("Failed to print message from hello driver: %d", ret);
        }

3. Cache the patch with cp samples/basic/blinky/src/main.c /tmp/main.c
4. Restore the repo with git restore samples/basic/blinky/src/main.c
5. Export the external module from Part A with export ZEPHYR_EXTRA_MODULES=<your_path>/zephyr-module
6. Do a pristine build with west build -b nrf5340dk/nrf5340/cpuapp samples/basic/blinky -p always
7. Apply the zephyr change to blinky with cp /tmp/main.c samples/basic/blinky/src/main.c
8. In the external module repository, apply the staged syscall changes

cp /tmp/hello_driver.h include/hello_driver.h
cp /tmp/hello_driver.c src/hello_driver.c

9. Back in the zephyr repository, do an incremental build and see the build failure west build -b nrf5340dk/nrf5340/cpuapp samples/basic/blinky

I verified the fix by replacing Part B step 1, checking out my branch git checkout test-module. This cherry-picks the blinky external driver integration on top of this PR's fix.
