[Linux] `MemoryPressureHandler::ReliefLogger::platformMemoryUsage()` result
is inconsistent
https://bugs.webkit.org/show_bug.cgi?id=306031
Reviewed by Miguel Gomez.
`MemoryPressureHandler::ReliefLogger::platformMemoryUsage()` on Linux
returns `MemoryUsage {processMemoryUsage(), memoryFootprint()}`. Both
functions call `currentProcessMemoryStatus()` internally and return
parts of the returned `ProcessMemoryStatus` structure, with the
difference that `memoryFootprint()` returns a cached value and
`processMemoryUsage()` not.
We can instead call `currentProcessMemoryStatus()` directly. This way
both values will be consistent with each other. It also avoids the
extra overhead of calling parsing `/proc/self/statm` twice.
