Add support for getDirectionality/isMirrored in Character

[AsheraCordova]

In my project I have reference to getDirectionality method on Character.

Instead of trying to patch what you don't understand, please, try to find a way to avoid these methods in your project, or at least avoid it in the part which is compiled with TeaVM

The pull request was inspired from the above library "https://github.com/wooorm/direction".

GenerateDirectionalityMap.java
GenerateIsMirroredMap.java

put
//start - getDirectionality
//end - getDirectionality

//start - isMirrored
//end - isMirrored

in TCharacter.java and
in
GenerateDirectionalityMap.java
GenerateIsMirroredMap.java

Point it to your file:
writeOrUpdateFile(out.toString(), "D:\Users\Kyra Consulting\git\konsoletyper-teavm\classlib\src\main\java\org\teavm\classlib\java\lang\TCharacter.java", "getDirectionality");

Mostly we need to find the ranges of code point in which the output changes starting from 1 to Character.MAX_CODE_POINT. Given that we are calling and caching the output of getDirectionality isMirrored and in array range this method I thought is bound to pass.

See if this is acceptable as we need to run this code generator once per release if we support newer jdks.
