fix(build): link vmStructs inline definitions in assertion-enabled builds

[rkennke]

Problem

crashProtectionActive() and cast_to() are declared inline in vmStructs.h — where the VMNMethod / cast accessors odr-use them inside assert(...) — but they are defined only in vmStructs.inline.h. A translation unit that includes the light vmStructs.h without the .inline.h counterpart therefore odr-uses those inline functions with no visible definition.

• In NDEBUG builds the asserts compile out, so the main release .so links fine.
• The gtest targets keep assertions on, so crashProtectionActive() is left unresolved at link time.

It surfaces first on hotspotStackFrame_aarch64.o (on x86_64 the reference is optimized away, so CI stayed green), which breaks every aarch64 gtest link — e.g.:

Undefined symbols for architecture arm64:
  "crashProtectionActive()", referenced from:
      VM::initProfilerBridge(...) in vmEntry.o
      HotspotStackFrame::unwindCompiled(...) in hotspotStackFrame_aarch64.o
      ...
ld: symbol(s) not found for architecture arm64

This is independent of any feature work — it reproduces on a clean main.

Fix

Include vmStructs.inline.h in the TUs that odr-use the accessors (hotspotStackFrame_aarch64.cpp, hotspotStackFrame_x64.cpp, vmEntry.cpp), matching the codebase's existing .h / .inline.h split. vmEntry.cpp's now-redundant direct vmStructs.h include is dropped since .inline.h pulls it in.

Verification

./gradlew :ddprof-lib:buildGtestRelease now links (previously failed on arm64); confirmed on macOS/aarch64.

LGTM!

I wonder if we should run asan/tsun regularly for each PR ...
