  [PassBuilder] Table-drive pass name printing (#202656)

Replace the macro-expanded raw_ostream operations in
PassBuilder::printPassNames with static pass-name arrays and two shared
noinline printing loops. Preserve the generated category order and the
exact spelling of parameterized pass names.

The change only executes when a client requests the pass-name listing;
normal pipeline parsing and optimization do not access the new tables or
helpers.

A stripped opt binary shrinks from 115,493,720 to 115,394,640 bytes,
saving 99,080 bytes. The linked __TEXT section shrinks by 98,304 bytes.

Work towards #202616
