[llvm-objcopy][WebAssembly] Allow --strip-debug to operate on relocatable files. (#102978)
This change is enough to allow `--strip-debug` to work on object files,
without breaking the relocation information or symbol table.
A more complete version of this change would instead reconstruct the
symbol table and relocation sections, but that is much larger change.
Bug: #102002

[WebAssembly][Objcopy] Write output section headers identically to inputs
Previously when objcopy generated section headers, it padded the LEB
that encodes the section size out to 5 bytes, matching the behavior of
clang. This is correct, but results in a binary that differs from the
input. This can sometimes have undesirable consequences (e.g. breaking
source maps).
This change makes the object reader remember the size of the LEB
encoding in the section header, so that llvm-objcopy can reproduce it
exactly. For sections not read from an object file (e.g. that
llvm-objcopy is adding itself), pad to 5 bytes.

[WebAssembly] Add WASM_SEC_LAST_KNOWN to BinaryFormat section types list [NFC]
There are 3 places where we were using WASM_SEC_TAG as the "last" known
section type, which requires updating (or leaves a bug) when a new known
section type is added. Instead add a "last type" to the enum for this
purpose.

[Objcopy][Wasm] Allow selecting known sections by name
Currently, only custom sections can be selected by operations that use section
names, because only custom sections have explicit names (whereas known sections
have names defined by the spec and only use their indices in the binary format).
This CL makes objdopy use the spec-defined names for these sections, allowing
them to be used in operations such as dumping and removal.
This is a prerequisite for fixing

[objcopy][NFC] Rename files to avoid clashing of archive members.
libtool uses file names to name members of an static library.
Files, located in different directories and having matching name,
would have the same name inside an archive. This is not a problem
for ld, but may be a problem for ar. This patch renames files
from ObjCopy library to avoid names clashing.
