  [SLPVectorizer] Support SLPVectorizer cases of tan across all backends (#95517)

This PR is intended to address the limited SLPVectorizer support of tan
raised in the comments of this PR:
https://github.com/llvm/llvm-project/pull/94559.

Right now emitting the tan intrinsisic allows you to vectorize tan, but
emitting the libfunc does not. to address this the libcall needs to be
mapped to the intrinsic. and the libcall and function name need to be
marked approriately so they can be optimized or defined as a call
lowering.
