  [NVPTX] Consolidate and cleanup various NVPTXISD nodes (NFC) (#145581)

This change consolidates and cleans up various NVPTXISD target-specific
nodes in order to simplify SDAG ISel. While there are some whitespace
changes in the emitted PTX it is otherwise a non-functional change.

NVPTXISD::Wrapper - This node was used to wrap external-symbol and
global-address nodes. It is redundant and has been removed. Instead we
use the non-target versions of these nodes and convert them
appropriately during ISel.

NVPTXISD::CALL - Much of the family of nodes used to represent a PTX
call instruction have been replaced by this new single node. It
corresponds to a single instruction and is therefore much simpler to
create and lower.
