Add minimal platform support documentation for powerpc-unknown-linux-gnuspe

Per https://github.com/rust-lang/rust/pull/137860#issuecomment-2692358259, add minimal platform support documentation, including a brief summary and links to more detailed information about this target.

The added documentation is minimal. This is somewhat similar to [powerpc-unknown-openbsd, which also has no target maintainer](https://doc.rust-lang.org/nightly/rustc/platform-support/powerpc-unknown-openbsd.html). The rest of the template is left to target maintainers.

I also updated powerpc-unknown-linux-muslspe platform support documentation and added link to powerpc-unknown-linux-gnuspe platform support documentation.

# powerpc-unknown-linux-gnuspe
**Tier: 3**
`powerpc-unknown-linux-gnuspe` is a target for Linux on 32-bit PowerPC
processors that implement the Signal Processing Engine (SPE), such as e500, and
uses a different ABI than standard `powerpc-unknown-linux-gnu`.
When building for other 32-bit PowerPC processors, use
`powerpc-unknown-linux-gnu` instead.
See also [Debian Wiki](https://wiki.debian.org/PowerPCSPEPort) for details on
this platform, and [ABI reference](https://web.archive.org/web/20120608163804/https://www.power.org/resources/downloads/Power-Arch-32-bit-ABI-supp-1.0-Unified.pdf)
for details on SPE ABI.
Note that support for PowerPC SPE by GCC was [removed in GCC 9](https://gcc.gnu.org/gcc-8/changes.html),
so recent GCC cannot be used as linker/compiler for this target.

There are currently no formally documented target maintainers.
