Int31 -> Int32

The 31 and 63 are pedantic and confusing: the functions should
be named for the type they return, same as all the others.
The lower-case n is inconsistent with Go's usual CamelCase
and especially problematic because we plan to add 'func N'.

This change undoes the restrictions added in CL 482079, which added a
blanket ban on using actions within JS template literal strings, and
adds logic to support actions while properly applies contextual escaping
based on the correct context within the literal.
Since template literals can contain both normal strings, and nested JS
contexts, logic is required to properly track those context switches
during parsing.

Some C APIs require the use or structures that contain pointers to
buffers (iovec, io_uring, ...). The pointer passing rules would
require that these buffers are allocated in C memory and to process
this data with Go libraries it would need to be copied.
In order to provide a zero-copy way to use these C APIs, this CL
implements a Pinner API that allows to pin Go objects, which
guarantees that the garbage collector does not move these objects
while pinned. This allows to relax the pointer passing rules so that
pinned pointers can be stored in C allocated memory or can be
contained in Go memory that is passed to C functions.
The Pin() method accepts pointers to objects of any type and
unsafe.Pointer. Slices and arrays can be pinned by calling Pin()
with the pointer to the first element. Pinning of maps is not
supported.
If the GC collects unreachable Pinner holding pinned objects it
panics. If Pin() is called with the other non-pointer types it
panics as well.
Performance considerations: This change has no impact on execution
time on existing code, because checks are only done in code paths,
that would panic otherwise. The memory footprint on existing code is
one pointer per memory span.

Add a struct called Source that holds the function, file and line
of a location in the program's source code.
When HandleOptions.AddSource is true, the ReplaceAttr function will
get an Attr whose key is SourceKey and whose value is a *Source.
We use *Source instead of Source to save an allocation. The pointer
and the value each cause one allocation up front: the pointer when it
is created, and the value when it is assigned to the `any` field of a
slog.Value (handle.go:283). If a ReplaceAttr function wanted to modify
a Source value, it would have to create a new slog.Value to return,
causing a second allocation, but the function can modify a *Source in
place.
TextHandler displays a Source as "file:line".
JSONHandler displays a Source as a group of its non-zero fields.
This replaces the previous design, where source location was always a
string with the format "file:line". The new design gives users more
control over how to output and consume source locations.
