arch: arm, arm64: Disable swi_tables.ld file when not required

[rakons]

This commit removes the need of swi_tables.ld file if the ISR table generator is not configured to use it.

Fixes #68508

For other to understand and for future references, then this is imprecise:

With this prefix the build works only for Ninja and does not
work propery for other build tools.

Please include something like the following information:

Linking in Zephyr / CMake.

• Ninja invokes linking directly from <build>.
• Make invokes linking form <build>/zephyr.

The linker default uses cwd for looking up INCLUDE directives if not found in list of includes.
Zephyr always adds <build>/zephyr as link include using CMake,
and this is passed to ld as -L<build>/zephyr therefore using INCLUDE isr_tables_swi.ld ensures it will be correctly found in all cases.

I made a comment in the original PR, but these changes are important enough they really need to go into the release notes. A separate PR can be raised for that, though.

And fixed spaces. But please take a note that we are not consistent about defined and space after it. Personally I prefer it anyway how @pdgendt suggested - just aligned previously my style to the one found in the near surrounding.
