Throw correct IllegalArgumentException from WolfCryptRandom.engineGenerateSeed()

[cconlon]

This PR correctly throws IllegalArgumentException from WolfCryptRandom.engineGenerateSeed() for input values that are negative or larger than wolfCrypt's supported size.

This also adds algorithm aliases (Hash_DRBG, DRBG) to match the existing HashDRBG implementation. This allows for better interop for applications using those other algorithm names.

JUnit tests are included to prevent regression on these changes.

This fixes OpenJDK SunJCE test: security/SecureRandom/EnoughSeedTest.java

Pull Request Overview

This PR enhances the WolfCryptRandom implementation by adding proper input validation to engineGenerateSeed() and introducing algorithm aliases for better interoperability. The changes ensure that negative values and values exceeding wolfCrypt's maximum block length properly throw IllegalArgumentException, which fixes compatibility with OpenJDK SunJCE tests.

• Added input validation to throw IllegalArgumentException for invalid seed generation parameters
• Introduced algorithm aliases (Hash_DRBG, DRBG) to match existing HashDRBG implementation
• Added comprehensive JUnit tests to prevent regression
