gralloc: Remove opaque types

Remove opaque types like size_t, uintptr_t, intptr_t to support
32bit and 64bit processes together.

When a 64bit process creates a handle and a 32bit process validates
the incoming ints against expected ints, opaque types lead to
different and mismatching values.

Always use unit64_t for base address for 32bit and 64bit SF.
Use unsigned int for offset and size, since ION uses that.
