[GR-64282] Espresso CDS: Module layer caching.

[graalvmbot]

This PR implements a subset of the CDS (Class Data Sharing) functionality from HotSpot into Espresso.
Ironically, there's no class meta-data included in the file since the Espresso implementation aims to speed up the creation of the boot ModuleLayer. HotSpot's CDS is older than Espresso itself and has accumulated additional features over time, some of which be integrated as well into Espresso.

Espresso's static archive should be located by default in JAVA_HOME/lib/truffle/classes.ejsa.
It can be generated at build time with java -truffle -Xshare:dump.
Espresso maps HotSpot's -Xshare:on|off|auto|dump as --java.CDS=on|off|auto|dump.
Custom archive path can be set similar to HotSpot's -XX:SharedArchiveFile=<path/to/classes.jsa> using --java.SharedArchiveFile=<path/to/classes.ejsa>.

Additional logging can be enabled with --log.java.CDS.level=ALL -Djdk.module.boot.usePerfData=debug.

Simple tests for Espresso native-ee standalone, power save mode (slow, but more stable):
java -truffle -Xshare:off Hello 480ms
java -truffle -Xshare:on Hello 233ms (48%)
HotSpot for reference:
java -server -Xshare:off Hello 107ms
java -server -Xshare:on Hello 66ms (61%)

On Espresso JVM (cold):
espresso -Xshare:off Hello 5907ms
espresso -Xshare:on Hello 4838ms (81%)
