[fix](fe) Update fe-core compiler release level from 8 to 17 (#63843)
### What problem does this PR solve?
Issue Number: close #63728
Problem Summary: FE depends on JDK 17 for compilation (parent pom set
`maven.compiler.source/target=17` since PR #62221), but fe-core's
`maven-compiler-plugin` still had `<release>8</release>` as a leftover
from PR #41417. This caused FE unit tests using JDK 17 APIs (e.g.,
`Random.nextLong(long)`) to fail at compile time. Additionally,
`PatternDescribableProcessor` declared
`@SupportedSourceVersion(SourceVersion.RELEASE_8)`, which is
inconsistent with the JDK 17 compilation target.
