Reland: [llvm-cov][WebAssembly] Read `__llvm_prf_names` from data segments (#112569)
On WebAssembly, most coverage metadata contents read by llvm-cov (like
`__llvm_covmap` and `__llvm_covfun`) are stored in custom sections
because they are not referenced at runtime. However, `__llvm_prf_names`
is referenced at runtime by the profile runtime library and is read by
llvm-cov post-processing tools, so it needs to be stored in a data
segment, which is allocatable at runtime and accessible by tools as long
as "name" section is present in the binary.
This patch changes the way llvm-cov reads `__llvm_prf_names` on
WebAssembly. Instead of looking for a section, it looks for a data
segment with the same name.
This reverts commit 157f10ddf2d851125a85a71e530dc9d50cb032a2 and fixes
PE/COFF `.lprfn$A` section handling.
