[Elixir] Fix generation issues and compilation warnings in Elixir generator (#18788)
* Format Elixir generator * Update Elixir reserved words * Update Elixir generator docs * Improve typespec generation to avoid double ".t" issues * Fix compilation warnings by changing reserved words to use suffix instead of underscore prefix * Include additional reserved words and handle words with leading underscores * Update samples and docs * Uses dataType instead of baseType for non-struct types * Generate elixir samples * Fixes issue with AnyType in a list * Generate elixir samples * Removes normalizeTypeName for arrays as they correct by getTypeDeclaration * CodeStyle --------- Co-authored-by: Michael Ramstein <michael@ramste.in>
