a4099fc756 AK: Try to avoid String allocation in FlyString(StringView)
If we're constructing a FlyString from a StringView, and we already
have a matching StringImpl in the table, use HashTable::find() to
locate the existing string without creating a temporary String.

1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

e265054c12 Everywhere: Remove a bunch of redundant 'AK::' namespace prefixes
This is basically just for consistency, it's quite strange to see
multiple AK container types next to each other, some with and some
without the namespace prefix - we're 'using AK::Foo;' a lot and should
leverage that. :^)

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.

d89582880e Kernel: Switch singletons to use new Singleton class
MemoryManager cannot use the Singleton class because
MemoryManager::initialize is called before the global constructors
are run. That caused the Singleton to be re-initialized, causing
it to create another MemoryManager instance.

Fixes #3226

35329400b8 AK: Implement a slightly better FlyString::operator==(String)
This was showing up in Browser profiles, which is silly, so write a new
version that doesn't create a temporary String object.

There are a whole bunch of these and long-term it would be nice to find
a way to share all the very similar logic instead of duplicating it.

fdfda6dec2 AK: Make string-to-number conversion helpers return Optional
Get rid of the weird old signature:

- int StringType::to_int(bool& ok) const

And replace it with sensible new signature:

- Optional<int> StringType::to_int() const

This creates a unified implementation of ends_with with case sensitivity
across String/StringView/FlyString.

e4b9cf9b6c AK: Some FlyString improvements
We're now clever enough to notice when we're constructing a FlyString
from a String that is actually already a FlyString. :^)

95cc4c7e74 AK: Add some string comparison operators
Some of these are very inefficient. It's nice to have some optimization
opportunities in the future though. :^)

7d862dd5fc AK: Reduce header dependency graph of String.h
String.h no longer pulls in StringView.h. We do this by moving a bunch
of String functions out-of-line.

4f72f6b886 AK: Add FlyString, a simple flyweight string class
FlyString is a flyweight string class that wraps a RefPtr<StringImpl>
known to be unique among the set of FlyStrings. The class is very
unoptimized at the moment.

When to use FlyString:

- When you want O(1) string comparison
- When you want to deduplicate a lot of identical strings

When not to use FlyString:

- For strings that don't need either of the above features
- For strings that are likely to be unique
