This adds the ability to recognize (and create ValueObjects for) boolean
literals ("true", "false") to DIL. This is a preliminary step to adding
type casting (and also for the ternary op).
This patch introduces `ScalarLiteralNode` without any uses by other
nodes yet. It also includes lexing and parsing for integer and floating
point numbers.
Reapplies #152308 with a fix.
This patch introduces `ScalarLiteralNode` without any uses by other
nodes yet. It also includes lexing and parsing for integer and floating

This patch fixes `-Wreturn-type` warnings which happens if LLVM is built
with GCC compiler (14.1 is used for detecting)
Warnings:
```
llvm-project/lldb/source/ValueObject/DILLexer.cpp: In static member function ‘static llvm::StringRef lldb_private::dil::Token::GetTokenName(Kind)’:
llvm-project/lldb/source/ValueObject/DILLexer.cpp:33:1: warning: control reaches end of non-void function [-Wreturn-type]

Technically, it is a bug in Clang (see #115345), however, UBSan with
Clang should detect these places, therefore it would be nice to provide
a return statement for all possible inputs (even invalid).
