  [RISCV] TableGen-erate RISC-V SDNodes (#138381)

This commit moves RISC-V to auto-generate its target-specific SDNode
types. The biggest change is that SDNodes can now be validated against
their expected type profiles, and that we don't need to edit several
different files when declaring a new one.

This takes Sergei's work in #119709 and "finishes" it - by moving the
final five RISCVISD opcodes into tablegen (including defining their
types), and by ensuring the tablegen has expected closing scope
comments.
