CryptoPkg/BaseCryptLib: make mVirtualAddressChangeEvent STATIC

Make mVirtualAddressChangeEvent STATIC to prevent it from conflicting
with other variables of the same name that may be defined in other
libraries (e.g., MdeModulePkg/Universal/Variable/RuntimeDxe)
This also removes the risk of mVirtualAddressChangeEvent being merged with
other uninitialized variables with external linkage by toolchains that perform
COMMON allocation.
