Introduce CLR_CMAKE_TARGET_APPLE_MOBILE for iOS/tvOS/MacCatalyst (#126833)

These three platforms share the same runtime constraints: static
linking, no fork(), no build tools, hybrid globalization, no console
signals, etc. Having each one listed individually in cmake conditions is
verbose and error-prone — PR #126550 accidentally disabled
FEATURE_CORPROFILER for tvOS alone, breaking unified-build tvOS legs.

Introduce CLR_CMAKE_TARGET_APPLE_MOBILE as an umbrella variable in
configureplatform.cmake, set when any of iOS, tvOS, or MacCatalyst is
the target. Replace ~30 'all three grouped' patterns across 11 cmake
files with the umbrella, reducing line noise and preventing future
divergence.

Per-platform variables are preserved where they genuinely differ:
- configurecompiler.cmake: TARGET_* C++ defines and compiler targets
- System.Security.Cryptography.Native.Apple: Swift platform names
- System.Net.Security.Native / corehost: tvOS gssapi exclusion
- System.Native: MacCatalyst pal_iossupportversion.m

Also fixes: sendfile exclusion was missing MacCatalyst (now covered by
APPLE_MOBILE), and the triplicated configure.cmake feature overrides for
iOS/MacCatalyst/tvOS are consolidated into one block.
