Remove managed reference tracking

[Martin-Molinero]

• Remove unrequired reference tracking causing exceptions on shutdown
  and a performance overhead

Test reproducing issue and asserting performance

from CLRImports import *

map_file_provider = LocalZipMapFileProvider()
map_file_provider.Initialize(DefaultDataProvider())
map_file_resolver = map_file_provider.Get(AuxiliaryDataKey.EquityUsa)

ae = datetime(2023, 2, 1)
tt = ""
method1 = map_file_resolver.ResolveMapFile
now = datetime.now()
for x in range(2000000):
        map_file = method1("AAPL", now)
        t = map_file.GetMappedSymbol(ae, tt)

print(f'Took: {datetime.now() - now}')
