MIPSr6: Set FSELECT Legal for f64 (#173591)

FIX: #172459
Since SETCC returns i1 in IR level, and SEL_D needs f64, currently, we
expand FSELECT to:
   MTC1_D64
   SEL
which may generate needless mfc1 and mtc1.

In this patch, we add FGR64CC Register type, and support F32 to F64 in
MipsSEInstrInfo::copyPhysReg.

[MLIR][Python] Add support of the walk pattern rewrite driver (#173562)

MLIR currently has three main pattern rewrite drivers (see
[https://mlir.llvm.org/docs/PatternRewriter/#common-pattern-drivers](https://mlir.llvm.org/docs/PatternRewriter/#common-pattern-drivers)):

* Dialect Conversion Driver
* Walk Pattern Rewrite Driver
* Greedy Pattern Rewrite Driver

Right now, we already support the greedy pattern rewrite driver in the C
API and Python bindings. This PR adds support for the walk pattern
rewrite driver. This lightweight driver, unlike the greedy driver, does
not repeatedly apply patterns; instead, it walks the IR once. API-wise,
the main change is adding the `walk_and_apply_patterns` function.

Note that the listener parameter is not supported now.
