This is a special form of `<string>` so doesn't need its own style value
type. It's used in a couple of font-related properties. For completeness
it's included in ValueType.

When a property is a "legacy name alias", any time it is used in CSS or
via the CSSOM its aliased name is used instead.
(See https://drafts.csswg.org/css-cascade-5/#legacy-name-alias)
This means we only care about the alias when parsing a string as a
PropertyID - and we can just return the PropertyID it is an alias for.
No need for a distinct PropertyID for it, and no need for LibWeb to
care about it at all.
Previously, we had a bunch of these properties, which misused our code
for "logical aliases", some of which I've discovered were not even
fully implemented. But with this change, all that code can go away, and
making a legacy alias is just a case of putting it in the JSON. This
also shrinks `StyleProperties` as it doesn't need to contain data for
these aliases, and removes a whole load of `-webkit-*` spam from the
style inspector.

amended to:
* resolve a conflict on height: in getComputedStyle-print-all.txt
* run prettier on CSSGeneratedFiles.md)
Instead of switching on the PropertyID and doing a boatload of
comparisons, we reorder the PropertyID enum so that all inherited
properties are in two contiguous ranges (one for shorthands,
one for longhands).
This replaces the switch statement with two simple range checks.
Note that the property order change is observable via
window.getComputedStyle(), but the order of those properties is
implementation defined anyway.

amended for stroke-linecap in getComputedStyle-print-all.txt)
For a long time, we've used two terms, inconsistently:
- "Identifier" is a spec term, but refers to a sequence of alphanumeric
characters, which may or may not be a keyword. (Keywords are a
subset of all identifiers.)
- "ValueID" is entirely non-spec, and is directly called a "keyword" in
the CSS specs.
So to avoid confusion as much as possible, let's align with the spec
terminology. I've attempted to change variable names as well, but
obviously we use Keywords in a lot of places in LibWeb and so I may
have missed some.
One exception is that I've not renamed "valid-identifiers" in
Properties.json... I'd like to combine that and the "valid-types" array
together eventually, so there's no benefit to doing an extra rename
now.
(cherry picked from commit 6a74b0164423d63904cf5a5b594772b595f57600;
very minorly amended to fix conflict in GenerateCSSKeyword.cpp caused
by #22870, and in libweb_generators.cmake due to us not having

This is `counter(name, style?)` or `counters(name, link, style?)`. The
difference being, `counter()` matches only the nearest level (eg, "1"),
and `counters()` combines all the levels in the tree (eg, "3.4.1").

The following command was used to clang-format these files:
clang-format-18 -i $(find . \
-not \( -path "./\.*" -prune \) \
-not \( -path "./Base/*" -prune \) \
-not \( -path "./Build/*" -prune \) \
-not \( -path "./Toolchain/*" -prune \) \
-not \( -path "./Ports/*" -prune \) \
-type f -name "*.cpp" -o -name "*.mm" -o -name "*.h")
There are a couple of weird cases where clang-format now thinks that a
pointer access in an initializer list, e.g. `m_member(ptr->foo)`, is a
lambda return statement, and it puts spaces around the `->`.
`JsonValue::to_byte_string` has peculiar type-erasure semantics which is
not usually intended. Unfortunately, it also has a very stereotypical
name which does not warn about unexpected behavior. So let's prefix it
with `deprecated_` to make new code use `as_string` if it just wants to
get string value or `serialized<StringBuilder>` if it needs to do proper
serialization.
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

Implemented by adding the extra 3-value syntax as its own case and only
running it when parsing background-position. I'm sure it could be
implemented in a smarter way but this is still a bunch less code than
before. :^)
This means `object-position` will no longer incorrectly accept the
3-value background-position syntax.
Remove the now-ambiguous and unused `position` enum while we're at it.
(This enum only existed as a hack.)
This commit makes it possible to let properties accept easing functions
as values, which will be used in a later commit to implement
animation-timing-function.
This solves the longhands must be initialized before shorthands
problem by just initializing the value when it is first requested.
This will be needed for background-position-x/y which is a longhand
of a longhand, which otherwise breaks the longhands before shorthands
rule.
Similar to POSIX read, the basic read and write functions of AK::Stream
do not have a lower limit of how much data they read or write (apart
from "none at all").
Rename the functions to "read some [data]" and "write some [data]" (with
"data" being omitted, since everything here is reading and writing data)
to make them sufficiently distinct from the functions that ensure to
use the entire buffer (which should be the go-to function for most
usages).
No functional changes, just a lot of new FIXMEs.
