install.texi: For amdgcn, clarify which llvm-* binaries are required
Also remove future tense for ROCm as 6.4.0 has been released in April 2025
and it supports generic architectures.
gcc/ChangeLog:
* doc/install.texi (amdgcn): Clarify which binaries must be the
LLVM version and which must be installed. Update version data for
ROCm for generic architectures.
