Use the `fuchsia_component` and `fuchsia_package` GN templates from the
Fuchsia SDK to package the `v8_unittests` test for Fuchsia. Give the
`v8_unittests` their own dedicated `.cmx` file, instead of depending on
`v8.cmx`.

This changeset include:
1. [prepare for migrate] move `cctest/compiler/value-helper.h`,
`cctest/compiler/c-signature.h`, and `cctest/compiler/call-tester.h` to
`test/common` directory because both `test-codegen` and a lot of cctest file
include it.
2. [prepare for migrate] separate the tester helper part of `test-codegen`
into a new `codegen-tester` file.
3. finally, migrate test-codegen.cc to `codegen-unittest.cc`

The existing version for paged spaces simply reset the freelist, which
doesn't work for tests that require actual objects in the space.
The version for new space also doesn't work because it assumes
everything after top is free space.
Fill the space with FixedArray by iterating over the freelist and
creating an object in place of each freelist entry.
This method actually fills the space, so that we can also use it to
force page promotion.

This CL refactors the implementation of inner pointer resolution, based
on the marking bitmap. MarkCompactCollector::FindBasePtrForMarking has
most of its code that processes the marking bitmap moved to a utility
function FindPreviousObjectForConservativeMarking, which iterates
backwards to find the closest previous object on the page that has been
marked.

This CL introduces a compile flag v8_enable_inner_pointer_resolution_osb
behind which lies the experimental implementation of the object start
bitmap. It disassociates the object start bitmap from the compile flag
v8_enable_conservative_stack_scanning. At the moment the former flag is
a prerequisite for the latter, as conservative stack scanning requires
some mechanism for inner pointer resolution and the object start bitmap
provides one such mechanism.

This merges the separate opcode name definitions from wasm-opcodes-inl.h
into the main opcode-defining macros in wasm-opcodes.h. This is simpler
(avoids a bunch of fairly complex macros) and easier to update when we
add new opcodes in the future.
The tests become obsolete because they would simply repeat the implementation.
