Fix S1215 FN: `GC.GetTotalMemory(forceFullCollection: true)` should not be called

[fiotti]

Description

GC.GetTotalMemory(forceFullCollection: true) calls GC.Collect() internally.

It might make sense to consider it equivalent to GC.Collect() and trigger a S1215.

Repro steps

GC.Collect(); // S1215: Refactor the code to remove this use of 'GC.Collect'.

GC.GetTotalMemory(true); // No warning.

Expected behavior

GC.Collect(); // S1215: Refactor the code to remove this use of 'GC.Collect'.

GC.GetTotalMemory(true); // S1215: Refactor the code to remove this use of 'GC.GetTotalMemory', or do not set 'forceFullCollection' to true.

Actual behavior

No warning.

Known workarounds

None.
