Rename SetSingleFuncCall() to InitMaterializedSRF()

Browse Source 
Per discussion, the existing routine name able to initialize a SRF
function with materialize mode is unpopular, so rename it.  Equally, the
flags of this function are renamed, as of:
- SRF_SINGLE_USE_EXPECTED -> MAT_SRF_USE_EXPECTED_DESC
- SRF_SINGLE_BLESS -> MAT_SRF_BLESS
The previous function and flags introduced in 9e98583 are kept around
for compatibility purposes, so as any extension code already compiled
with v15 continues to work as-is.  The declarations introduced here for
compatibility will be removed from HEAD in a follow-up commit.

The new names have been suggested by Andres Freund and Melanie
Plageman.
