java: Remove async-profiler "buildids" support

[Jongy]

This was not maintained and the current code is incorrect. When we get to implement the backend part - we can revive this on the agent side.

See my comment here. We're returning a char * where actually a NativeFunc is expected. I don't want to fix the code now because this feature is not used anyway.

That's the range-diff for the async-profiler change:

 1:  f03014d =  1:  f03014d Replace semicolon in method descriptors to vertical bar, since a semicolon is already used to separate between methods
 2:  56daea2 =  2:  56daea2 Remove the "Profiling started" message
 3:  e406f18 =  3:  e406f18 Remove the "Profiling stopped" message
 4:  7a4312d =  4:  7a4312d Compile statically with libstdc++
 5:  52692de =  5:  52692de Build jattach statically
 6:  0edb237 <  -:  ------- Enocde buildid+offset of unknown symbols in the frame (#1)
 7:  0c51507 =  6:  e6abbed Build fdtransfer statically
 8:  114a86f =  7:  4699370 Compile statically with libgcc
 9:  dbc8e7e =  8:  1bef4f5 Force link with memcpy@GLIBC_2.2.5 on x86_64
10:  86595ea =  9:  4018ebb Fix -static-* args passed only in non-MERGE case :(
11:  6f38e45 = 10:  ee5acc1 Close standard streams after forking in fdtransfer
12:  ef1d3b3 = 11:  1eed7a1 Generate randomized fdtransfer path per async-profiler invocation (#635)
13:  48fba55 = 12:  dcfe236 -static-libstdc++ only on musl
14:  008a8cf = 13:  7b51a01 Do not use ELF NODELETE flag because of glibc bug
