CVE-2023-5174, and CVE-2023-5176.

* gnu/packages/gnuzilla.scm (icu4c-73-promise): New variable.
(all-mozilla-locales, %icecat-base-version, %icecat-build-id): Update.
(icecat-source): Update gnuzilla commit, base version, and hashes.
(icecat-minimal)[inputs]: Use icu4c-73-promise.  Remove nss.
[native-inputs]: Use rust-cbindgen-0.24, llvm-15, clang-15, and node-lts.
[arguments]<configure-flags>: Comment out "--with-system-nss".
[description]: "IceCat 102" --> "IceCat 115".
(%icecat-locales): Update.
(all-mozilla-102-locales, %icecat-102-base-version)
(%icecat-102-version, icecat-102-source): New variables
bound to the old values, for use by icedove.
(icedove-source): Ues 'icecat-102-source'.
(make-l10n-package)[arguments]<phases>: Simplify reference to
'#$locales, and thereby eliminate the unnecessary dependence on
%icedove-locales by icecat-l10n, and similarly on %icecat-locales by
icedove-l10n.
[native-inputs]: Use node-lts.
* gnu/packages/patches/icecat-makeicecat.patch: Adapt to new upstream.
