This patch changes the way frames created from scripted affordances like
Scripted Threads are displayed. Currently, they're marked artificial
which is used usually for compiler generated frames.

This patch changes that behaviour by introducing a new synthetic
StackFrame kind and moves 'artificial' to be a distinct StackFrame
attribut.

On top of making these frames less confusing, this allows us to know
when a frame was created from a scripted affordance.

This patch addresses 2 issues:
1. It makes registers available on non-crashed threads all the time
2. It fixes arm64 registers parsing for registers that don't use the `x`
prefix (`fp` -> `x29` / `lr` -> `x30`)

This patch adds support to the haswell sub-architecture (x86_64h) to
scripted processes.

This patch makes interactive mode as the default when using the crashlog
command. It replaces the existing `-i|--interactive` flag with a new
`-m|--mode` option, that can either be `interactive` or `batch`.

By default, when the option is not explicitely set by the user, the
interactive mode is selected, however, lldb will fallback to batch mode
if the command interpreter is not interactive or if stdout is not a tty.

This also adds some railguards to prevent users from using interactive
only options with the batch mode and updates the tests accordingly.

This is a followup to #122440, which changed function-relative
calculations to use the function entry point rather than the lowest
address of the function (but missed this usage). Like in #116777, the
logic is changed to use file addresses instead of section offsets (as
not all parts of the function have to be in the same section).

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.
