Subject: [PATCH v7 3/4] fs: unicode: Rename utf8-core file to unicode-core

utf8data.h_shipped has a large database table which is an auto-generated
decodification trie for the unicode normalization functions and it is not
necessary to carry this large table in the kernel.
Goal is to make UTF-8 encoding loadable by converting it into a module
and adding a unicode subsystem layer between the filesystems and the
utf8 module.

This layer will load the module whenever any filesystem that
needs unicode is mounted.
Currently, only UTF-8 encoding is supported but if any other encodings
are supported in future then the layer file would be responsible for
loading the desired encoding module.

Rename the file name from utf8-core to unicode-core for transformation of
utf8-core file into the unicode subsystem layer file and also for better
Implementation for unicode-core file to act as layer will be added in the
future patches.
