[LLDB] Add draft docstrings for SBSaveCoreOptions (#123132)

SBSaveCoreOptions has been around for awhile now, so I decided to draft
up some Docstrings describing the functionality better. Some of my
wording sounded a bit clunky due the optionality of each method call so
I would greatly appreciate feedback.

Includes the new method in #122541 so I will merge this as a follow up.

+"A container to specify how to save a core file.
+
+SBSaveCoreOptions includes API's to specify the memory regions and threads to include
+when generating a core file. It extends the existing SaveCoreStyle option.
+
+* eSaveCoreFull will save off all thread and memory regions, ignoring the memory regions and threads in
+the options object.
+
+* eSaveCoreDirtyOnly pages will capture all threads and all rw- memory regions, in addition to the regions specified
+in the options object if they are not already captured.
+
+* eSaveCoreStackOnly will capture all threads, but no memory regions unless specified.
+
+* eSaveCoreCustomOnly Custom defers entirely to the SBSaveCoreOptions object and will only save what is specified. 
+  Picking custom and specifying nothing will result in an error being returned.
+
+Note that currently ELF Core files are not supported.
