ArmPkg/Semihostlib: Rename semi-hosting open option 

Change mnemonic SEMIHOST_FILE_MODE_CREATE with mnemonic SEMIHOST_FILE_MODE_UPDATE.
The bit referred to by this mnemonic is for the semi-hosting open mode code the
equivalent of the + in the ISO C fopen mode terminology. This allows to select the
so called update mode for which both read and write are allowed on the open file.
The mnemonic SEMIHOST_FILE_MODE_UPDATE is more in line with the ISO C fopen mode
terminology. A description of the ISO C fopen modes can be found here :
