Introduce TARGET_CLONES_ATTR_SEPARATOR for RISC-V
Some architectures may use ',' in the attribute string, but it is not
used as the separator for different targets. To avoid conflict, we
introduce a new macro TARGET_CLONES_ATTR_SEPARATOR to separate different
clones.
As an example, according to RISC-V C-API Specification [1], RISC-V allows
',' in the attribute string in the "arch=" option to specify one more
ISA extensions in the same target function, which conflict with the
default separator to separate different clones. This patch introduces
TARGET_CLONES_ATTR_SEPARATOR for RISC-V and choose '#' as the separator,
since '#' is not allowed in the target_clones option string.
