RFR: 8333793: Improve BootstrapMethodInvoker for ConstantBootstraps and ProxyGenerator

[Claes Redestad]

This PR refactors type matching in BootstrapMethodInvoker and adds a few types, seeking to improve bootstrap overheads of some ConstantBootstraps and in particular the ProxyGenerator condys generated for e.g. annotation proxies since [JDK-8332457](https://bugs.openjdk.org/browse/JDK-8332457)

I've adjusted the micro-benchmark added by JDK-8332457 to not only generate a proxy but also call into one of the proxied methodt (`Object::hashCode`). 

Running org.openjdk.bench.java.lang.reflect.ProxyGenBench as a one-off startup benchmark sees significant improvement (-9% instructions, -6% cycles):

Name             Cnt           Base          Error            Test          Error         Unit  Change
Perfstartup-JMH   20        154,000 ±        8,165         148,000 ±       23,164        ms/op   1,04x (p = 0,352 )
  :.cycles            925335973,200 ± 47147600,262   842221278,800 ± 46836254,964       cycles   0,91x (p = 0,000*)
  :.instructions     2101588857,600 ± 81105850,361  1966307798,400 ± 22011043,908 instructions   0,94x (p = 0,000*)
  :.taskclock               291,500 ±       16,494         262,000 ±       15,328           ms   0,90x (p = 0,000*)
  * = significant

Number of classes loaded drops from 1096 to 1092

Running the micro regularly shows no significant difference:

Name                              Cnt   Base   Error    Test   Error  Unit  Change
ProxyGenBench.generateAndProxy100  10 26,827 ± 8,954  26,855 ± 7,531 ms/op   1,00x (p = 0,991 )
  * = significant
