Re-enable FEATURE_CORPROFILER for tvOS to match iOS/MacCatalyst

PR dotnet#126550 disabled FEATURE_CORPROFILER for tvOS but left iOS,
MacCatalyst, and Android commented out (profiler still enabled).
There is no reason to single out tvOS from its sibling Apple mobile
platforms. They should be treated as a package deal.

The uncommented 'AND NOT CLR_CMAKE_TARGET_TVOS' line removed profiler
fields from the Thread struct on tvOS, making the hardcoded
OFFSETOF__Thread__m_pInterpThreadContext in asmconstants.h wrong
(0x2b8 vs actual 0x228), breaking all 3 tvOS legs in unified-build.

Comment out the tvOS line to match iOS/MacCatalyst/Android, keeping
the profiler enabled until all mobile platforms disable it together.

Fixes internal unified-build tvOS failures on main (build 2946990).
