For use in rlang_new_ctxt_pronoun() where we don't poke into the pronoun environment at all, which makes it slightly faster and allocate less memory. new_data_mask() now shows up as allocating 0 memory by profmem.
I was tempted to make this what happens if you supply 0 in r_alloc_environment(), but that felt wrong because it creates a non-hashed environment and is different from what R_NewEnv() does (by using the "default" size of 29)
