RFR(S) 8252481 Remove excessive include of memTracker.hpp

[Ioi Lam]

https://bugs.openjdk.java.net/browse/JDK-8252481
http://cr.openjdk.java.net/~iklam/jdk16/8252481-excessive-memTracker-hpp.v01/

memTracker.hpp is included by 847 out of 971 .o files in the HotSpot build.

Most of these are caused by these header files:

jfrAllocation.hpp -- completely unnecessary

allocation.hpp, allocation.inline.hpp -- the use of CURRENT_PC can be 
avoid by calling this function instead:

char* AllocateHeap(size_t size,
                    MEMFLAGS flags,
                    AllocFailType alloc_failmode /* = 
AllocFailStrategy::EXIT_OOM*/) {
   return AllocateHeap(size, flags, CALLER_PC);
}


======================

Before:

$ cd build/linux-x64
$ find hotspot -name \*.o | wc -l
971
$ find hotspot -name \*.d | xargs grep -l memTracker.hpp | wc -l
847
$ find hotspot -name \*.d | xargs cat | wc -l
528505

After:

$ find hotspot -name \*.d | xargs grep -l memTracker.hpp | wc -l
95
$ find hotspot -name \*.d | xargs cat | wc -l
512731

The total number of included header files has reduced for about 3%

512731 / 528505 = 0.970
