[12_0_X]Fix on compilation issues with DMR, GC and MTS validation scripts.

[TomasKello]

PR description:

Introduces several fixes on tracker alignment validation scripts and macros which appeared to throw errors during compilation. Errors are mostly due to type conversion issues (TString <-> std::string) and broken forward declaration of imported classes and a few typos.
No changes in output are expected.

PR validation:

Changed macros were successfully tested during Alignment Validation on data and MC.
