API Change ShaderCode/ShaderUtil: Enable optional mutable shader source / generalize shader source storage type to CharSequence[]

Benefits:
  - Allows code injection and general shader source editing (before compilation)

  - Uses mutable StringBuilder only if editing is intended, hence reduces memory footprint
    and String conversion at compilation in such case.

- ShaderCode.create(..) factory methods add nw attribute 'mutableStringBuilder'
  if true method returns a mutable StringBuilder instance
  which can be edited later on at the costs of a String conversion when passing to
  'glShaderSource(int, int, String[], IntBuffer)'.
  If <code>false</code> method returns an immutable <code>String</code> instance,
  which can be passed to {@link GL2ES2#glShaderSource(int, int, String[], IntBuffer)}
  at no additional costs.

- New 'edit' methods in ShaderCode: '
   - int insertShaderSource(int shaderIdx, String tag, int fromIndex, CharSequence data);
   - int insertShaderSource(int shaderIdx, int position, CharSequence data);
