This is a fix for the crash issue in 64-bit ARM [#32175][1].
When targeting Android 11 and above, 64-bit ARM platforms
have the 'Tagged Pointer' feature enabled by default which
causes memory allocated using the system allocator to have
a non-zero 'tag' set in the highest byte of heap addresses.
This is incompatible with SpiderMonkey which assumes that
only the bottom 48 bits are set and asserts this at various
points.
Both Servo and Gecko have a similar architecture where
the pointer to a heap allocated DOM struct is encoded as
a JS::Value and stored in the DOM_OBJECT_SLOT (reserved
slot) of the JSObject which reflects the native DOM struct.
As observed in #32175, even Gecko crashes with `jemalloc`
disabled which suggests that support for using the native
system allocator with tagged pointers enabled by default
is not present at the moment.

Simply installing 'clang' installs the default version of Clang for
Linux. For instance, the command: 'apt install clang' installs
'clang-14' in Ubuntu 22.04.
It might be possible that a more recent version of clang is
already installed in the system. For instance, package 'clang-17'.
In the case a 'clang' binary is already installed in the system, skip
the installation of 'clang'.

It reports that by standard convention, from_* methods should not take any `&self` parameter

This allows sharing font templates, fonts, and platform fonts across
layout threads. It's the first step toward storing web fonts in the
layout versus the shared `FontCacheThread`. Now fonts and font groups
have some locking (especially on FreeType), which will probably affect
performance. On the other hand, we measured memory usage and this saves
roughly 40 megabytes of memory when loading servo.org based on data from
the memory profiler.
