[Clang][OpenMP] Fix runtime problem when explicit map both pointer and pointee (#92210)

ponter int *p for following map, test currently crash.

  map(p, p[:100]) or map(p, p[1])

Currly IR looks like
// &p, &p, sizeof(int), TARGET_PARAM | TO | FROM
// &p, p[0], 100sizeof(float) TO | FROM

Worrking IR is
// map(p, p[0:100]) to map(p[0:100])
// &p, &p[0], 100*sizeof(float), TARGET_PARAM | TO | FROM | PTR_AND_OBJ

The change is add new argument AreBothBasePtrAndPteeMapped in
generateInfoForComponentList

Use that to skip map for map(p), when processing map(p[:100]) generate
map with right flag.
