Improve notation of BuiltinTrancheNames

Use C99 designated initializer syntax for array elements, instead of
writing the position in a comment.  This is less verbose and much more
readable.  Akin to cc150596341e.

One disadvantage is that the BuiltinTrancheNames array now has a hole of
51 NULLs -- previously, the array elements were shifted 51 elements
 downward to avoid this.  This can be fixed by merging the
IndividualLWLockNames array into BuiltinTrancheNames, which would occupy
those 51 pointers, but because it requires some arguably ugly Meson
hackery, it's left for later.
