Dump likely class in gtDispTree

[EgorBo]

Since cast helpers may expand with PGO in late phases, it makes sense to print their top likely classes in JITDUMP, example:

*  JTRUE     void  
\--*  EQ        int   
   +--*  CALL help ref    CORINFO_HELP_ISINSTANCEOFCLASS (66% likely 'Progam+DerivedClass2')
   |  +--*  CNS_INT(h) long   0x7ff96d187878 class Progam+DerivedClass1
   |  \--*  LCL_VAR   ref    V02 loc0         
   \--*  CNS_INT   ref    null

Also, unify MAX_CAST_GUESSES with MAX_GDV_TYPE_CHECKS

Pull Request Overview

This PR enhances debugging capabilities by printing the top likely classes in JITDUMP and unifies constants used for type checks.

• Adds an extra parameter (verboseLogging) to control verbose logging in the type check candidate selection.
• Replaces uses of MAX_CAST_GUESSES with MAX_GDV_TYPE_CHECKS to standardize limits across casts.
• Extends debug output in gtDispTree to optionally print profiling information for cast helpers.

• Verify that MAX_GDV_TYPE_CHECKS is defined consistently across all build configurations and update surrounding comments to fully reflect the unification with MAX_CAST_GUESSES.

const int maxTypeChecks = min(comp->getGDVMaxTypeChecks(), MAX_GDV_TYPE_CHECKS);
