PEL: Support for going between PELs & registry
Add tables that allow one to go between how a PEL field actually shows
up in the PEL (raw bytes) and how it shows up in the message registry (a
string enumeration). The tables also have a column to show a string
description of that value that can be used by the parser, though for now
those descriptions are all left at "TODO".
There only needs to be a table for a PEL field when there is a
corresponding message registry field that is a string enumeration, so
that when code looks up an error in the message registry it knows what
to fill in the PEL with.
Also provide APIs to look up a row in the table by either the PEL value
or the message registry value.
