init: ported Trim_Prefix_{String,Unicode} primitive function

Since a number of level 1 Hestia libraries use string functions, we have to port its primitive ones into HestiaKERNEL library package. Hence, let's do this. This patch ports Get_Prefix_{String,Unicode} primitive function into HestiaKERNEL library in init/ directory.
