[IR][PatternMatch] Make `m_Checked{Int,Fp}` accept `Constant *` output instead of `APInt *`

The `APInt *` version is pretty useless as any case one needs an
`APInt *` out, they could just replace whatever they have the
`m_Checked...` lambda with direct checks on the `APInt`.

Leaving other helpers such as `m_Negative`, `m_Power2`,
etc... unchanged as the `APInt` out version is used mostly for
convenience and rarely change functionality when converted output a
`Constant *`.

Closes #91377
