Subject: [PATCH v8 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 unless it is required by
the filesystem during boot time.

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 then load the module whenever any filesystem that
needs unicode is mounted or utf8 can also be built into the kernel incase
it is required by the filesystem during boot time.

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
understanding.
Implementation for unicode-core file to act as layer will be added in the
future patches.
