linker: section_tags: missing include

[Finomnis]

Describe the bug
Using section tags like __dtcm_noinit_section should resolve to:

__attribute__((section(".dtcm_noinit"), used))

However, due to a missing include, they resolve to:

__attribute__((section("_DTCM_NOINIT_SECTION_NAME"), used))

... failing to move the variable to the proper section and causing the following warning:

ld.bfd.exe: warning: orphan section `_DTCM_NOINIT_SECTION_NAME' from `app/libapp.a(main.c.obj)' being placed in section `_DTCM_NOINIT_SECTION_NAME'

To Reproduce

• Checkout Zephyr in a workspace
• modify samples/hello_world/src/main.c to contain:

  #include <stdio.h>
  
  #include <zephyr/linker/section_tags.h>
  
  __dtcm_bss_section int data[1024];
  
  int main(void)
  {
  	// Just some usage of the variable to prevent optimizing it away
  	for (int i = 0; i < 1024; i++) {
  		data[i] = i * i;
  	}
  
  	int result = 0;
  	for (int i = 0; i < 1024; i++) {
  		result += data[i];
  	}
  
  	printf("Result: %d", result);
  
  	return 0;
  }

• Run west build -b mimxrt1170_evk/mimxrt1176/cm7 samples/hello_world/

Impact
All projects that use <zephyr/linker/linker_sections.h> directly fail to link to the appropriate section.
There is no indication anywhere that this header cannot be used directly. (at least none that I could find)

Additional context
This wasn't reproducible on any of the examples before, because the ones that are susceptible (like samples/boards/mimxrt1170_evk_cm7/magic_addr/) include <zephyr/kernel.h>, which indirectly pulls in the required header to resolve the defines:

• #include <zephyr/kernel.h>
• #include <zephyr/kernel_includes.h>
• #include <zephyr/linker/sections.h>

Workarounds
Including <zephyr/kernel.h> or <zephyr/linker/sections.h> in user code fixes this issue.

Environment (please complete the following information):

• OS: Windows 11
• Zephyr SDK 0.16.8
• Used commit f9e3b65 (Zephyr v3.7.0-rc3 + main)
