Reland: [libc] Move off_t and stdio macros to proxy hdrs (#98384)
reland of https://github.com/llvm/llvm-project/pull/98215
Additionally adds proxy headers for FILE and the fopencookie types
The arm32 build has been failing due to redefinitions of the off_t type.
This patch fixes this by moving off_t to a proper proxy header. To do
this, it also moves stdio macros to a proxy header to hopefully avoid
including this proxy header alongside this public stdio.h.
