[C++][Parquet][IPC] Use capped memory pool when fuzzing

[pitrou]

Describe the enhancement requested

OSS-Fuzz will trigger an out-of-memory crash if the allocated memory goes beyond a predefined limit (usually 2560 MB, though that can be configured). For Parquet and IPC, it is legitimate to allocate a lot of memory when decompressing data, though, so that can happen on both valid and invalid input files.

Unfortunately, OSS-Fuzz checks for this memory limit not by instrumenting malloc and having it return NULL when the limit is reached, but by checking allocated memory periodically from a separate thread. This can be solved by implementing our custom allocator with an upper limit, exactly how the mupdf project did in google/oss-fuzz#1830
