* Group changes in recent releases by lexers

* Format changelog file for consistency

The 'record' keyword defines a new kind of record class.
'enum' was moved as the same level as the other types, as enums are also kind of classes.
Added 'var' as an alternative to 'def' for defining variables and such.

The [inline classes feature](https://github.com/dart-lang/language/blob/main/working/1426-extension-types/feature-specification-inline-classes.md) this was part of is now obsolete and will not be part of the language. It will likely be replaced by [extension types](https://github.com/dart-lang/language/blob/main/accepted/future-releases/extension-types/feature-specification.md).

* bpf: highlight signed type keywords

Signed type keywords such as s16 have always been supported by BPF but
recently became more frequent. They were missing in the original lexer
so this commit adds them, with an example.

* bpf: highlight simpler call syntax

The lexer already supports the following syntax for call instructions:

    call bpf_skb_load_bytes#1234

but a simpler syntax without the number at the end is now also possible.
This commit adds support for it, with an example.

* bpf: highlight all byte-swapping instructions

The original lexer was missing support for the little-endian
byte-swapping instructions le{16,32,64}. This commit adds them, together
with the new bswap{16,32,64} instructions. The later are unconditional
byte-swapping instructions, meaning they don't depend on the
architecture.

* bpf: fix highlight of negative hexadecimal numbers

Hexadecimal literals can also have a sign in BPF. This commit fixes this
error in the lexer and adds a corresponding example.

* bpf: highlight hexadecimal jump offsets

The offset of BPF jump instructions is now sometimes displayed in
hexadecimal format. This commit adds support for that, together with an
example. It also adds an example to cover the syntax where the jump has
both an offset literal and an offset label (ex. "+1 <LBB0_2>").

* bpf: highlight long jumps

Jump instructions with a 32-bit offset are displayed as "gotol" instead
of "goto".
