  Change zos-ppa1-name attr to be the name used in ppa1 (#208870)

Change the meaning of the `zos-ppa1-name` attribute to pass the name of
the function to use in the PPA1. The symbol name used in the PAA1 will
be:
- if the function has the `zos-ppa1-name` attribute, use that value. An
empty string will be mean don't add the name to the PPA1
- otherwise  use the function name.

The behaviour for asm labels and `#pragma map` (PR coming shortly) is to
use the function name used in the source code in the PPA1. A follow on
PR for clang will set `zos-ppa1-name` to the mangled name ignoring asm
label to implement the non-empty string part of the first bullet.
