[NFC] Extract DWARFCFIProgram into separate files (#139326)

CFIPrograms' most common uses are within debug frames, but it is not
their only use. For example, some assembly writers encode them by hand
into .cfi_escape directives. This PR extracts code for them into its own
files, setting them up to be evaluated from outside debug frames
themselves.

One in a series of NFC DebugInfo/DWARF refactoring changes to layer it
more cleanly, so that binary CFI parsing can be used from low-level
code, (such as byte strings created via .cfi_escape) without circular
dependencies. The final goal is to make a more limited dwarf library
usable from lower-level code.
