Add more test configuration to StaticLayoutPerfTest

This CL adds more perf test case for StaticLayout.

The "testCreate" and "testCreateRandom" is renamed to
"testCreate_FixedText_NoStyle_Greedy_NoHyphenation" and
"testCreate_RandomText_NoStyled_Greedy_NoHyphenation".

The test configuration is now constructed with underscores.

- FixedText/RandomText
  The text contents to be used for performing StaticLayout generation.
  FixedText means using the same text.
  RandmText means generating random text.
  This configuration is mainly seeing how LayoutCache performs well.

- NoStyle/Styled
  The text styles to be used for performing StaticLayout generation.
  NoStyle means using not styled text. (CharBuffer is used).
  Styled means using randomly styled text.

- Greedy/Balanced
  The line breaking strategy to be used performing StaticLayout generation.
  Greedy means using Greedy algorithm.
  Balanced means that the line length is balanced.

- Hyphenation/NoHyphenation
  The word can be hyphenated for performing StaticLayout generation.
  Hyphenation means enable hyphenation.
  NoHyphenation means disable hyphenation.

This CL doesn't add all combination since some configuration doesn't
affect others. For example, Styled/NoStyled and
Greedy/Balanced/Hyphenation/NoHyphenation are independent.
