Enable Hot Reload API on Linux (#48497)

Enable Hot Reload API on Linux

Only define EnC_SUPPORTED for vm/ee on xplat. Doesn't enable the ENC ICorDebug API.

Enable hotreload api tests on Linux/MacOS. API not implemented on arm/arm64

Remove all the ENC_DELTA_HACK code. Remove more ENC_DELTA_HACK code from ilasm
