Harmonize IAR C-STAT headers between the first-time analysis
and subsequent builds, which uses cached results.
It also removes spurious relative paths such as `"../` and
`..\` that might appear after a new line followed by a double quote.
Effectively this will display paths relative to CMAKE_SOURCE_DIR,
similarly to the IDE, which display paths relative to $PROJ_DIR$.
Update the IAR tests to match the new C-STAT outputs.
The <LANG>_ICSTAT co-compile appended --source= only when another
linter (tidy/cpplint/cppcheck/pvs) was also active, so a C-STAT-only
target ran `icstat analyze "" -- ...` with an empty file argument.
Add icstat to the --source= condition so C-STAT gets the real path.

Refactoring in commit 019f0f8b32 (ARCHITECTURE_ID: Save persistently
even if empty, 2025-03-13, v4.1.0-rc1~499^2~1) accidentally dropped
part of the variable name in `CMakeASMCompiler.cmake`.

The IAR Assemblers seem to be missing some built-in target-identifier
symbols. Instead, identify the affected target architectures by using
their respective `__TID__` (Target Identifier) built-in symbols. Also
make sure the test has an IAR Assembly implementation for each target.
Fixes: #26267
