This adds a few asserts to the property TableGen backend to prevent
mismatches between property types and their default values. This
would've prevented a copy-paste mistake we discovered downstream.
Right now our Properties.inc only generates the initializer for the
options list but not the array declaration boilerplate around it. As the
array definition is identical for all arrays, we might as well also let
the Properties.inc generate it alongside the initializers.
Unfortunately we cannot do the same for enums, as there's this magic
ePropertyExperimental, which needs to come at the end to be interpreted
correctly. Hopefully we can get rid of this in the future and do the
same for the property enums.

Splitting the different logic is cleaner and we it will be easier
to implement the enum emitting (which otherwise would have to
reimplement the Record parsing).

Summary:
Right now our CommandOptions.inc only generates the initializer for the options list but
not the array declaration boilerplate around it. As the array definition is identical for all arrays,
we might as well also let the CommandOptions.inc generate it alongside the initializers.
This patch will also allow us to generate additional declarations related to that option list in
the future (e.g. a enum class representing the specific options which would make our
handling code less prone).
This patch also fixes a few option tables that didn't follow our naming style.

We dynamically allocate the option validator which means we
can't mark this list of OptionDefinitions as constexpr. It's also
more complicated than necessary.

The printEscapedString would escape newlines by their ASCII values
instead of prefixing them with a `\`. Remove the escaping logic and
escape the strings in the definition file.

Property definitions are currently defined in a PropertyDefinition array
and have a corresponding enum to index in this array. Unfortunately this
is quite error prone. Indeed, just today we found an incorrect merge
where a discrepancy between the order of the enum values and their
definition caused the test suite to fail spectacularly.
Tablegen can streamline the process of generating the property
definition table while at the same time guaranteeing that the enums stay
in sync. That's exactly what this patch does. It adds a new tablegen
file for the properties, building on top of the infrastructure that
Raphael added recently for the command options. It also introduces two
new tablegen backends: one for the property definitions and one for
their corresponding enums.
It might be worth mentioning that I generated most of the tablegen
definitions from the existing property definitions, by adding a dump
method to the struct. This seems both more efficient and less error
prone that copying everything over by hand. Only Enum properties needed
manual fixup for the EnumValues and DefaultEnumValue fields.

We currently emit the option groups twice if Groups<[1,2,3]> is
used in the tablegen. This leads to compilation errors. This
patch just removes the line that accidentially emits the option
group a second time.

Summary:
When doing standalone builds, you could potentially be building against
an llvm which also built lldb. If this were the case, you'd be
attempting to build this target twice.

Summary:
We currently have man large arrays containing initializers for our command options.
These tables are tricky maintain as we don't have any good place to check them for consistency and
it's also hard to read (`nullptr, {}, 0` is not very descriptive).
This patch fixes this by letting table gen generate those tables. This way we can have a more readable
syntax for this (especially for all the default arguments) and we can let TableCheck check them
for consistency (e.g. an option with an optional argument can't have `eArgTypeNone`, naming of flags', etc.).
Also refactoring the related data structures can now be done without changing the hundred of option initializers.
For example, this line:
```
{LLDB_OPT_SET_ALL, false, "hide-aliases", 'a', OptionParser::eNoArgument, nullptr, {}, 0, eArgTypeNone, "Hide aliases in the command list."},
```
becomes this:
```
def hide_aliases : Option<"hide-aliases", "a">, Desc<"Hide aliases in the command list.">;
```
For now I just moved a few initializers to the new format to demonstrate the change. I'll slowly migrate the other
option initializers tables in separate patches.
