Fixes #3161

Clang Static Analyzer reproducers could miss headers when the recorded build command used GCC/G++, because TU dependency collection followed the original GCC command and therefore GCC-specific conditional includes.

This change:

• uses CodeChecker’s existing GCC-to-Clang command transformation for dependency collection,
• uses Clang/Clang++ dependency commands only for ClangSA reproducers,
• preserves the original recorded build commands in the reproducer metadata and compilation database,
• keeps C/C++ language handling intact,
• avoids introducing a new GCC flag blacklist.

Regression coverage includes:

• GCC vs Clang conditional headers,
• GCC-only flags such as -fno-var-tracking-assignments,
• correct preservation of original commands,
• command/action association when filtering or CTU reorders build actions.

Validation:

• 5/5 TU collector tests passed
• relevant analyzer command / option parser tests passed
• git diff --check passed
• pycodestyle passed
