Conditionally build `wasm-component-ld`

This commit updates the support for the `wasm-component-ld` tool from rust-lang#126967 to conditionally build rather than unconditionally building it when LLD is enabled. This support is disabled by default and can be enabled by one of two means:

* the `extended` field in `config.toml` which dist builders use to build a complete set of tools for each host platform.
* a `"wasm-component-ld"` entry in the `tools` section of `config.toml`.

Neither of these are enabled by default meaning that most local builds will likely not have this new tool built. Dist builders should still, however, build the tool.

 Fix enabling wasm-component-ld to match other tools

It was [pointed out recently][comment] that enabling `wasm-component-ld` as a host tool is different from other host tools. This commit refactors the logic to match by deduplicating selection of when to build other tools and then using the same logic for `wasm-component-ld`.

While here I also fixed a typo pointed out in rust-lang#126967 (review)

Here are all the changes. I went through them one-by-one and confirmed
that they should not be affecting us. In paritcular, we explicitly set
rust.lld = false (because we want to use the lld that ships with clang),
so the change in default does not affect us.

There have been changes to x.py since you last updated:
  [INFO] New option `build.lldb` that will override the default lldb binary path used in debuginfo tests
    - PR Link rust-lang/rust#124501
  [INFO] The compiler profile now defaults to rust.debuginfo-level = "line-tables-only"
    - PR Link rust-lang/rust#123337
  [WARNING] `rust.lld` has a new default value of `true` on `x86_64-unknown-linux-gnu`. Starting at stage1, `rust-lld` will thus be this target's default linker. No config changes should be necessary.
    - PR Link rust-lang/rust#124129
  [WARNING] Removed `dist.missing-tools` configuration as it was deprecated long time ago.
    - PR Link rust-lang/rust#125535
  [WARNING] `llvm.lld` is enabled by default for the dist profile. If set to false, `lld` will not be included in the dist build.
    - PR Link rust-lang/rust#126701
  [WARNING] `debug-logging` option has been removed from the default `tools` profile.
    - PR Link rust-lang/rust#127913
  [INFO] the `wasm-component-ld` tool is now built as part of `build.extended` and can be a member of `build.tools`
    - PR Link rust-lang/rust#127866
  [INFO] Removed android-ndk r25b support in favor of android-ndk r26d.
    - PR Link rust-lang/rust#120593
  [WARNING] For tarball sources, default value for `rust.channel` will be taken from `src/ci/channel` file.
    - PR Link rust-lang/rust#125181
  [INFO] New option `llvm.libzstd` to control whether llvm is built with zstd support.
    - PR Link rust-lang/rust#125642
  [WARNING] ./x test --rustc-args was renamed to --compiletest-rustc-args as it only applies there. ./x miri --rustc-args was also removed.
    - PR Link rust-lang/rust#128841
  [INFO] The `build.profiler` option now tries to use source code from `download-ci-llvm` if possible, instead of checking out the `src/llvm-project` submodule.
    - PR Link rust-lang/rust#129295
