Bundled LLVM is never built when llvm-config is specified in
config.toml, ie PORT_LLVM, and base system LLVM doesn't support
wasm32-unknown-unknown triple. Restore the previous behaviour of
using clang from the LLVM port when PORT_LLVM is enabled. Also
really fix the ${LLVM_VERSION} logic, as the variable is from
USES=llvm.

Did not initially notice the added ${LLVM_VERSION} to denote minimum
required PORT_LLVM version, but privatise to avoid collision with
USES=llvm's ${LLVM_VERSION} logic.

- Drop WASM option as it requires llvm from ports

Put back rustdoc in _RUST_TOOLS, rustdoc is an integral part of cargo
and has no connection with DOCS.

PR:		285381,285840
Tested by:	mikael,pkubaj

LLVM 20 support currently only exists in trunk.

While here:
 - remove rustdoc from _RUST_TOOLS, it has to be added only when
   DOCS option is enabled
 - add DOCS to OPTIONS_DEFAULT [1]
 - building docs on armv7 is fixed

PR:		285381 [1]

A bug [1] prevents documentation from being compiled on this
platform, disable it until it's fixed in a release branch.

Cargo uses curl-rust and git2-rs (which uses curl-rest as well).
Unfortunately, git2-rs calls openssl_probe::init_ssl_cert_env_vars()
unconditionally which breaks the process environment by setting an invalid
value for SSL_CERT_DIR and then the system default truststore is circumvented,
resulting in certificate validation errors even if certctl(8) manages
everything nicely.

Upstream Rust always requires SSE2 for x86.  But back in 2017[^1][^2] we
patched lang/rust to disable SSE2 for i386.  At the time, it was
reported that some people were still using non-SSE2 capable hardware.
More recently, LLVM bugs have been discovered[^3][^4] that can result in
rounding bugs and reduced accuracy when using f64 on non-SSE hardware.
In weird cases, they can even cause wilder unpredictable behavior, like
segfaults.

Revert our change for the sake of Pentium 4 (and later) users.  But add
an SSE2 option.  Disabling it will allow the port to be used on Pentium
3 and older CPUs.

LLVM 19 support only starts in Rust 1.82; this restriction will be
removed once the update is committed.

This reverts commit 52c0456dd5ec259ac94ee401db79c7ad3569f914.

I have no idea what lead to this commit into devel/RStudio and
lang/rust-nightly to be made.
