Remove 32-bit x86 specific code from the HotSpot Serviceability Agent following the removal of 32-bit x86 support.
- Removed x86-specific implementations and ifdef blocks. - Renamed files with X86 in the name when they are also used from AMD64, e.g. `X86Frame` → `AMD64Frame`. - Cleaned up platform detection logic in `PlatformInfo`. - Updated documentation references. ------------- Commit messages: - Clean up Hotspot SA after 32-bit x86 removal Changes: https://git.openjdk.org/jdk/pull/27844/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=27844&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8351194 Stats: 2747 lines in 45 files changed: 607 ins; 2094 del; 46 mod Patch: https://git.openjdk.org/jdk/pull/27844.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/27844/head:pull/27844 PR: https://git.openjdk.org/jdk/pull/27844
