Using CPP map instead of string

Basic working setup to use CPP Map instead of basic string type
Settings copied from accessibilityState (fromRawValue) and from
importantForAccessibility (toString)

the CPP convertRawProps will use two functions to convert the prop:
- fromRawValue which takes as param the prop RawValue
- toString or toBoolean, to*** which convert the RawValue to
  String/Boolean/Number

The error was triggered for missing conversion from RawValue
(AccessibilityUnit field hours) toString.

(std::string) accessibilityUnit.hours would call
toString(accessibilityUnit.hours)

Tasks Details:
Complete draft CPP accessibilityUnit settings:Commit the changes and pushAdd more clear log statements and further verify value passed to  accessibilityUnitLog the value passed from javascript in conversion.hAdd changes from PR #2Change logic in conversion.h to add the value passed from javascript
--
Change the type from String to Hash in PR #3:Plan next tasksFind a prop that uses the Hash type (for ex accessibilityState)Start with a clear git statusCopy the CPP settings from accessibilityState
Parse accessibilityUnit hours value to a string type. The value is already string, but in CPP is not mapped to string.importantForAccessibility uses 2 conversions, fromRawValue and toString. fromRawValue parses the props importantForAccessibility, while toString converts the value from IMPORTANT_FOR_ACCESSIBILITY to string.Follow the same implementation fromRawValue(IMPORTANT_FOR_ACCESSIBILITY), but avoid adding their toString(Important_For_Accessibility) conversion.Pass a static string auto hours = “10”;
