[lldb] Implement (SB)Function::GetInstructions for discontinuous functions (#122933)

The main change is to permit the disassembler class to process/store
multiple (discontinuous) ranges of addresses. The result is not
ambiguous because each instruction knows its size (in addition to its
address), so we can check for discontinuity by looking at whether the
next instruction begins where the previous ends.

This patch doesn't handle the "disassemble" CLI command, which uses a
more elaborate mechanism for disassembling and printing instructions.

This reverts commit 2526d5b1689389da9b194b5ec2878cfb2f4aca93, reapplying
ba14dac481564000339ba22ab867617590184f4c after fixing the conflict with
#117532. The change is that Function::GetAddressRanges now recomputes
the returned value instead of returning the member. This means it now
returns a value instead of a reference type.

[lldb] Expose discontinuous functions through SBFunction::GetRanges (#117532)

SBFunction::GetEndAddress doesn't really make sense for discontinuous
functions, so I'm declaring it deprecated. GetStartAddress sort of makes
sense, if one uses it to find the functions entry point, so I'm keeping
that undeprecated.

I've made the test a Shell tests because these make it easier to create
discontinuous functions regardless of the host os and architecture. They
do make testing the python API harder, but I think I've managed to come
up with something not entirely unreasonable.
