[CLI] fix command ignores --include / --exclude file filter

[hashiiiii]

The --include and --exclude options on the fix command do not filter which files are fixed. All files in the solution are modified regardless of the specified patterns.

The analyze command correctly respects these options (fixed in #1459).

Reproduction: https://github.com/hashiiiii/roslynator-fix-include-bug-repro

roslynator fix ./TestSolution.sln \
  --include "ProjectA/**" \
  --supported-diagnostics CA1822

Expected: Only files under ProjectA/ are fixed.
Actual: Files under ProjectB/ are also fixed.

In CodeFixer.cs, FileSystemFilter is not checked in GetFixableDiagnostics or FixDiagnosticsAsync. It is only checked in GetDiagnosticsAsync, which runs after the fix loop for reporting purposes.

I created a PR following the same approach as #1459 .
