[mlir][math] Initial support for fastmath flag attributes for Math dialect.
Added arith::FastMathAttr and ArithFastMathInterface support for Math dialect
floating point operations.
This change-set creates ArithCommon conversion utils that currently
provide classes and methods to aid with arith::FastMathAttr conversion
into LLVM::FastmathFlags. These utils are used in ArithToLLVM and
MathToLLVM convertors, but may eventually be used by other converters
that need to convert fast math attributes.
Since Math dialect operations use arith::FastMathAttr, MathOps.td now
has to include enum and attributes definitions from Arith dialect.
To minimize the amount of TD code included from Arith dialect,
I moved FastMathAttr definition into ArithBase.td.

[lldb-vscode] Send Statistics Dump in terminated event
This patch will gather debug info & breakpoint info from the statistics dump (from `(SBTarget.GetStatistics())` func) and send to DAP in terminated event.
The statistics content can be huge (especially the `modules`) and dumping in full JSON can create delay in the IDE's debugging UI. (For more details, please read: https://github.com/llvm/llvm-project/commit/
7bbd0fba986c241162b77b7e424ad82bc7e17b41 ). Hence, we will filter out large contents before returning it in terminated event.
It will keep all the metadata fields (those starts with "total"). For large contents, it uses the opt-out strategy. Currently it only removes the "modules" field. This way every time a new top-level field being added, we will be able to capture them from DAP log without changing lldb-vscode.
The DAP terminated event should look like
```
{
"event":"terminated",
"seq":0,
"statistics": {
"memory": <JSON string>
"targets": <JSON string>, // it's a JSON array, breakpoints info included in each target
<metadata_key: value> // pairs
},
"type":"event"
}
```
All the info above will be append to statistics field in the terminated event
Test Plan
Debugged a simple hello world program from VSCode. Exit debug session in two ways: 1) run to program exit; 2) user initiated debug session end (quit debugging before program exit).
Check DAP log and see both debug sessions have statistics returned in terminated event.
Here's an example when debugging the test program:
```
