Import bounds_safety.h across all of webputils, with one exception being
dsp.h, since it's imported by webputils.h in one place. Also prepend
WEBP_ASSUME_UNSAFE_INDEXABLE_ABI to every webputil file to indicate to
the compiler that every pointer should be treated as __unsafe_indexable.
We also need to replace memcpy/memset/memmove with the unsafe variants
WEBP_UNSAFE_*, as memcpy/memset/memmove require bounded/sized pointers.
With this change, all of libwebputils (and libwebp) should build with
-DWEBP_ENABLE_FBOUNDS_SAFETY=true

(Debian clang-format version 19.1.7 (3+build4)) with `--style=Google`.
Manual changes:
* clang-format disabled around macros with stringification (mostly
assembly)
* some inline assembly strings were adjusted to avoid awkward line
breaks
* trailing commas, `//` or suffixes (`ull`) added to help array
formatting
* thread_utils.c: parameter comments were changed to the more common
/*...=*/ style to improve formatting
The automatically generated code under swig/ was skipped.

This is a refinement of
654bfb04 Avoid nullptr arithmetic in VP8BitReaderSetBuffer
and removes an unneeded/redundant check in 2 of the 3 calls to this
function:
* VP8InitBitReader: `start` is guaranteed to be non-NULL
* CopyParts0Data: `start` is allocated and checked
In `DoRemap()` `last_start` will be NULL before the partitions are
parsed. This is the only call that was missing a check. The offsetting
of a NULL pointer in `VP8BitReaderSetBuffer` was harmless in this case
as the bitreader will not be used meaningfully until there is enough
data to begin decoding partition 0. In that case the bitreader will be
initialized by `ParsePartitions()` and updated by `DoRemap()` when more
data is available.

Semi-automatically taking the the misc-include-cleaner warnings
by clang-tidy and fixing files to be self-contained.

This is a follow up to:
ee8e8c62 Fix member naming for VP8LHistogram
This better matches Google style and clears some clang-tidy warnings.
This is the final change in this set. It is rather large due to the
shared dependencies between dec/enc.

and define it to true for __aarch64__ and Win Arm64 + Visual Studio.
Microsoft's compiler (cl.exe) does not define __aarch64__, but relies on
_M_ARM64 & _M_ARM64EC

this avoids duplicates between these trees and dsp/, e.g., enc/tree.c,
dec/tree.c, making pulling the whole library source tree into one target
possible
