LOG: [lldb][Docs] Various style improvements to the tutorial (#90594)

* Replace "we" with either "you" (when talking to the reader) or "lldb"
(when talking about the project).
* Refer to lldb as lldb not LLDB, to match what the user sees on
the command line (I am going to come back later and put the proper name in places where it's talking about the projects themselves)
* Remove a bunch of contractions for example "won't". Which don't (pun
intended) seem like a big deal at first but even I as a native English
speaker find the text clearer with them expanded.
* Use RST's plain text highlighting for keywords and command names.
* Split some very long lines for easier editing in future.

 ========
 
-Here's a short precis of how to run lldb if you are familiar with the gdb
-command set. We will start with some details on lldb command structure and
-syntax to help orient you.
+This document describes how to use lldb if you are already familiar with
+gdb's command set. We will start with some details on lldb command structure and
+syntax.
 
 Command Structure
 -----------------
 
-Unlike gdb's command set, which is rather free-form, we tried to make the lldb command syntax fairly structured. The commands are all of the form:
+Unlike gdb's quite free-form commands, lldb's are more structured. All commands
+are of the form:
 
 ::
 
    <noun> <verb> [-options [option-value]] [argument [argument...]]
 
-The command line parsing is done before command execution, so it is uniform
-across all the commands. The command syntax for basic commands is very simple,
-arguments, options and option values are all white-space separated, and
-either single or double-quotes (in pairs) are used to protect white-spaces
-in an argument.  If you need to put a backslash or double-quote character in an
-argument you back-slash it in the argument. That makes the command syntax more
-regular, but it also means you may have to quote some arguments in lldb that
-you wouldn't in gdb.
+The command line parsing is done before command execution, so it is the same for
+all commands. The command syntax for basic commands is very simple.
 
-There is one other special quote character in lldb - the backtick.
+* Arguments, options and option values are all white-space separated.
+* Either single ``'`` or double-quotes ``"`` (in pairs) are used to protect white-spaces
+  in an argument.
+* Escape backslashes and double quotes within arguments should be escaped
+  with a backslash ``\``.
+
+This makes lldb's commands more regular, but it also means you may have to quote
+some arguments in lldb that you would not in gdb.
+
+There is one other special quote character in lldb - the backtick `````.
 If you put backticks around an argument or option value, lldb will run the text
 of the value through the expression parser, and the result of the expression
-will be passed to the command.  So for instance, if "len" is a local
-int variable with the value 5, then the command:
+will be passed to the command.  So for instance, if ``len`` is a local
+``int`` variable with the value ``5``, then the command:
 
 ::
 
    (lldb) memory read -c `len` 0x12345
 
-will receive the value 5 for the count option, rather than the string "len".
-
+Will receive the value ``5`` for the count option, rather than the string ``len``.
 
 Options can be placed anywhere on the command line, but if the arguments begin
-with a "-" then you have to tell lldb that you're done with options for the
-current command by adding an option termination: "--". So for instance, if you
-want to launch a process and give the "process launch" command the
-"--stop-at-entry" option, yet you want the process you are about to launch to
-be launched with the arguments "-program_arg value", you would type:
+with a ``-`` then you have to tell lldb that you are done with options for the

+
+So for instance, if you want to launch a process and give the ``process launch``
+command the ``--stop-at-entry`` option, yet you want the process you are about
+to launch to be launched with the arguments ``-program_arg value``, you would type:
 
 ::
 
    (lldb) process launch --stop-at-entry -- -program_arg value
 
 We also tried to reduce the number of special purpose argument parsers, which
-sometimes forces the user to be a little more explicit about stating their
-intentions. The first instance you'll note of this is the breakpoint command.
-In gdb, to set a breakpoint, you might enter
