add mips32r6 and mips64r6 target_arch detection

This PR introduces `"mips32r6"` and `"mips64r6"` as valid `target_arch` values, and would be the arch values used by Tier-3 targets `mipsisa32r6-unknown-linux-gnu`, `mipsisa32r6el-unknown-linux-gnu`, `mipsisa64r6-unknown-linux-gnuabi64` and `mipsisa64r6el-unknown-linux-gnuabi64`.

This PR is made for rust-lang/rust#112374.

This PR has a corresponding [MCP](rust-lang/compiler-team#632) waiting for review.

mips64r6 has the same ABIs, syscall conventions, and various magic numbers as mips64 does. So this PR just adds mips64r6 to all mips64 detection macros. Similarly, mips32r6 share their ABIs, syscall conventions and various magic with mips, so the PR just adds mips32r6 to where mips is to be detected.
