47f5a3ea9a HackStudio: Add 'pause debuggee' button
This button sends a SIGSTOP to the debugged process, which pauses it.
The debuggee can be resumed with the 'continue' button.

6e5b1f5819 HackStudio: Add progress bar to Debugger initialization
During Debugger initialization, most of the time is spent creating
DebugInfo objects for the libraries that the program has loaded.

d43a7eae54 LibCore: Rename File to DeprecatedFile
As usual, this removes many unused includes and moves used includes
further down the chain.

26250fe14a LibDebug: Add static attach() function
This function is similar to exec_and_attach(), but instead of spawning
a new process and debugging it, it attaches to an existing process.

57dc179b1f Everywhere: Rename to_{string => deprecated_string}() where applicable
This will make it easier to support both string types at the same time
while we convert code, and tracking down remaining uses.

One big exception is Value::to_string() in LibJS, where the name is
dictated by the ToString AO.

6e19ab2bbc AK+Everywhere: Rename String to DeprecatedString
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

31bd5b1a02 AK+Userland: Stub out code that isn't currently implemented on AARCH64
Even though this almost certainly wouldn't run properly even if we had
a working kernel for AARCH64 this at least lets us build all the
userland binaries.

c8585b77d2 Everywhere: Replace single-char StringView op. arguments with chars
This prevents us from needing a sv suffix, and potentially reduces the
need to run generic code for a single character (as contains,
starts_with, ends_with etc. for a char will be just a length and
equality check).

No functional changes.

3f3f45580a Everywhere: Add sv suffix to strings relying on StringView(char const*)
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).

No functional changes.

6d64b13a1b LibDebug+Everywhere: Avoid void* -> FlatPtr -> void* dance
And limit the `void*` to the functions that interface the system (i.e.
ptrace wrappers).
This generally makes the code less riddled with casts.

a02d8e5710 LibDebug: Add optional setup_child() callback to debugger
If set, this callback gets called right after fork() in the child
process.

It can be used by the caller if it wants to perform some logic in the
child process before it starts executing the debuggee program.

7950f5cb51 LibDebug: Add ProcessInspector base class
ProcessInspector is an abstract base class for an object that can
inspect the address space of a process.

Concrete sub classes need to implement methods for peeking & poking
memory and walking the loaded libraries.

It is currently only implemented by DebugSession.

587f9af960 AK: Make JSON parser return ErrorOr<JsonValue> (instead of Optional)
Also add slightly richer parse errors now that we can include a string
literal with returned errors.

This will allow us to use TRY() when working with JSON data.

bb4bb3c2f4 LibDebug: Enable parsing libgcc_s.so
Now that our DWARF 5 support is nearly feature-complete, there is no
reason anymore to special-case this library, as we can process it just
fine.

c78838c2d2 LibDebug: Use the first memory segment of a library as the ELF's base
When parsing the libraries of the debugee process, we previously
assumed that the region that's called `<library name>: .text` was also
the base of the ELF file.

However, since we started linking with `-z separate-code`, this is no
longer the case - our executables have a read-only segment before the
.text segment, and that segment is actually at the base of the ELF.

This broke inserting breakpoints with the debugger since they were
inserted at a wrong offset.

To fix that, we now use the address of the first segment in the memory
map for the ELF's base address (The memory map is sorted by address).

f364fcec5d LibRegex+Everywhere: Make LibRegex more unicode-aware
This commit makes LibRegex (mostly) capable of operating on any of
the three main string views:
- StringView for raw strings
- Utf8View for utf-8 encoded strings
- Utf32View for raw unicode strings

As a result, regexps with unicode strings should be able to properly
handle utf-8 and not stop in the middle of a code point.
A future commit will update LibJS to use the correct type of string
depending on the flags.

fc6d051dfd AK+Everywhere: Add and use static APIs for LexicalPath
The LexicalPath instance methods dirname(), basename(), title() and
extension() will be changed to return StringView const& in a further
commit. Due to this, users creating temporary LexicalPath objects just
to call one of those getters will recieve a StringView const& pointing
to a possible freed buffer.

To avoid this, static methods for those APIs have been added, which will
return a String by value to avoid those problems. All cases where
temporary LexicalPath objects have been used as described above haven
been changed to use the static APIs.

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
