devel/wasi-libc: update to sdk-34

Changes:	https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-34
		https://github.com/WebAssembly/wasi-sdk/releases/tag/wasi-sdk-33

- sync CMAKE_ARGS from wasi-sdk
- consolidate wasi-libc's plists, they have been identical after cmake transition
- bump all existing WASI toolchain ports

Consumer PORTREVISIONs to be bumped

wasi: consistently use the wasm32-wasip1 triple

The WebAssembly community have reclaimed wasm32-wasi, without suffix,
for a future WASI 1.0 standard. The first version of WASI, 0.1, is
now wasm32-wasip1 in triple form, WASI 0.2 is wasm32-wasip2, etc.
Starting LLVM 22 the non-suffixed form is deprecated, aligning with
Rust and Go:

https://blog.rust-lang.org/2024/04/09/updates-to-rusts-wasi-targets/

The Mozilla build system's WASI checks always pass -Werror so
configure fails when the non-suffixed target/triple is passed using
LLVM 22:

Mozilla bug: https://bugzilla.mozilla.org/show_bug.cgi?id=2023597

Bump all WASI ports for the new triple. Adjust consumers accordingly
but do not bump, since non-suffixed and p1 are identical as a
transition measure.

wasi: update to latest commit past sdk-22

devel/wasi-libc is now flavourised per supported LLVM version. Each
flavour includes/copies the corresponding clang's stdarg.h and
stddef.h instead of simply using the latest clang release.

Technically upstream dropped support for LLVM < 18, but the commit
doing so admittedly operated under an uncertain assumption. LLVM
17 is still supported in these ports for the benefit of Rust and
gecko@ ports, which specify LLVM 17 minimum, and to facilitate LTO
with that version. LLVM 19 is also supported in this version, with
the corresponding ports to be committed separately.

wasi: update libc to sdk-20 and modularise LLVM bits

wasi-libcxx and wasi-compiler-rt now meta ports (similar to u-boot);
the build process is the same for each LLVM version so child ports
are minimal. Minimum supported LLVM version is 12, thus its
corresponding child ports are resurrected and LLVM 11 child ports
are removed.

Since all supported LLVM versions are made available at once, remove
restriction in bsd.gecko.mk and switch to USES=llvm throughout. LTO
on gecko ports should now work with later LLVM versions so long as
${DEFAULT_VERSIONS} is set properly and matches the LLVM used in
rust (if not using the PORT_LLVM option).
