bug(#3481): removed globals-to-abstracts.xsl + fixed indents in to-java.xsl

Ref: #3481

In this PR I removed globals-to-abstract.xsl. Now such global EO object

3.14 > pi

is transpiled to such java class:

public final class EOpi extends PhOnce {
  /**
   * Ctor.
   */
  public EOpi() {
    super(
      () -> {
        Phi ret = Phi.Φ.take("org").take("eolang").take("number");
        ret = new PhCopy(ret);

          Phi ret_1 = Phi.Φ.take("org").take("eolang").take("bytes").copy();
          ret_1 = new PhWith(ret_1, 0, new PhDefault(new byte[] {(byte) 0x40, (byte) 0x09, (byte) 0x21, (byte) 0xFB, (byte) 0x54, (byte) 0x44, (byte) 0x2D, (byte) 0x18}));

        ret = new PhWith(ret, 0, ret_1);
        ret = new PhSafe(ret, "org.eolang.math.pi", 29, 0, "Φ.org.eolang.math.pi");
        return ret;
      }
    );
  }
}

As you may see - it's just lazy phi object as it supposed to without any unnecessary attributes.

Also I fixed indents in to-java.xsl. Now it looks more readable

UPD: fixed flaky thread safety problem related to accessing single HashMap inside StickyBiFunc from multiple threads in ShakeMojo and TranspileMojo
