CryptoPkg: Fix memcpy alias prototype to match the aliaseeHEADmaster

The memcpy alias in IntrinsicLib declares its count parameter as
unsigned int while the aliasee __memcpy uses size_t. On 64-bit targets
these are different widths. clang 23 diagnoses this through
-Wattribute-alias:

  CopyMem.c:29:17: warning: alias and aliasee have different types
  'void *(void *, const void *, unsigned int)' and
  'void *(void *, const void *, size_t)' [-Wattribute-alias]

and builds that treat warnings as errors fail, e.g. OVMF built with
the CLANGDWARF toolchain in Yocto.

Declare the alias with size_t so both signatures agree.
