Legacy Hermes support is no longer needed since 0.86 branch has been cut. This removes all dead code behind `!defined(HERMES_V1_ENABLED)` guards and the CMake infrastructure that set the HERMES_V1_ENABLED compile definition.
…solution Since legacy Hermes is no longer supported, remove the hermesV1Enabled toggle from the Gradle plugin, version.properties, and all build scripts. HERMES_V1_VERSION_NAME is renamed to HERMES_VERSION_NAME as the single Hermes version. CMake flags like HERMESVM_HEAP_HV_MODE are now unconditional.

Remove the RCT_HERMES_V1_ENABLED environment variable and all conditional logic in the CocoaPods/Ruby files. The podspec now always reads HERMES_VERSION_NAME, uses V1 source files, and omits legacy inspector subspecs. The HERMES_V1_ENABLED=1 preprocessor define is no longer set since no C++ code checks for it.
