RFR: 8360558: Use hex literals instead of decimal literals in math intrinsic constants

[Mohamed Issa]

A simple change to use hex literals instead of decimal literals in the constant arrays of the x86 cbrt and tanh stubs. The JTREG tests listed below were used to verify correctness. The baseline build used is [OpenJDK v26-b17](https://github.com/openjdk/jdk/releases/tag/jdk-26%2B17).

1. `jtreg:test/jdk/java/lang/Math/CubeRootTests.java`
2. `jtreg:test/jdk/java/lang/Math/HyperbolicTests.java`
