[0.4.14][RTL] Optimize RtlpFindAndCommitPages CORE-14588

Browse source 
A squashed backmerge of 3 commits authored by Thomas Faber.
They do help to speed up RosBE2.1.6 within ReactOS.
'configure' runs faster by ~ factor 5.
'ninja bootcd -j1' runs faster by ~ factor 2.
I considered back-porting that a necessity because we
considerably lost speed over the last years in those scenarios.
I tested, and it works well also in the 0.4.14RC.

Use LastEntryInSegment to speed up RtlpFindAndCommitPages. CORE-14588

Add and populate LastEntryInSegment. CORE-14588

Create a define for the common members of HEAP and HEAP_SEGMENT. CORE-14588

The code relies on these members matching up, so it's confusing for them
to be duplicated.
