Building on https://chromium-review.googlesource.com/c/v8/v8/+/1349243,
which asserted on calls to GetChars() that weren't in a
DisallowHeapAllocation scope, this CL takes a reference to the scope
in order to provide static protection in all builds.

This CL adds OnFailure::DUMP_ON_FAILURE representing a scope where base::
DumpWithoutCrash is called when V8 execution is detected. As V8 can't call base
functions, this CL also adds Platform::DumpWithoutCrash.

Store the bits of a small type into the lower bits
of a pointer type that are free due to alignment.
Furthermore, reordering of members to reduce size of some classes.

Instead, it is supposed to just return an empty context if it failed.
Also don't invoke interceptors (we don't for the parts that deserialize
from the snapshot anyways).

This internalization was not necessary, since the rewriting does not use
the .result name string.

The subsequent internalization is still needed, so to simplify later
refactoring, this CL also adds "releasing" of the disallow scopes and
uses them here immediately before the second internalize. Notably, this
means that the rewriting is now also in the disallow scopes.

Driveby: Remove isolate from the rewriter's processor constructor.

V8 is collecting a growing amount of fuzzers, all of which take substantial
space on the bots and in chromium build archives. This CL improves that
situation by allowing component (shared library) builds for almost all fuzzers.

The parser fuzzer is handled as an exception since it would require exporting a
large number of additional functions.

A component build results in about a 50-100x improvement in file size for each
fuzzer (~50M-100M to around 1.1M).

This enables linter checking for "readability/namespace" violations
during presubmit and instead marks the few known exceptions that we

This removes the DisallowAllocationFailure assertion scope which mostly
coincided with the AlwaysAllocateScope anyways. Access to the bitfield
in the Isolate was not synchronized and hence the AlwaysAllocateScope
was not thread-safe in debug mode, now it is.

The thread local key for assert scopes can be lazily initialized and
should be independent of the Isolate initialization. Also cleanup the
assert-scope.{cc,h} implementation while I was at it.
