Coding - Refactor RWStepAP214 module to use custom hasher for string_view types (#888)

Browse Source 
- Introduced StringViewHasher for efficient hashing of std::string_view using OCCT utilities.
- Updated THE_TYPENUMS and THE_TYPESHOR maps to utilize StringViewDataMap with the new hasher.
- Modified initialization functions to accept the new map type for better type safety and clarity.
