[compiler-rt] Set the ZX_VMO_RESIZABLE option for zx_vmo_create

Currently VMO in Zircon create using the zx_vmo_create is resizable by default, but we'll be changing this in the future, requiring an explicit flag to make the VMO resizable. Prepare for this change by passing ZX_VMO_RESIZABLE option to all zx_vmo_create calls that need resizable VMO. Differential Revision: https://reviews.llvm.org/D61450 llvm-svn: 359803
