Reland: [PA] Add partition_alloc_optimized_debug to partition_alloc.gni.

Make allocator_shim and raw_ptr also built with optimized_speed
for debug and component build on linux.

(for sheriff) Regarding chromium:1455341, locally built
component & debug browser_tests on Linux and ran
PlatformAppBrowserTest.
AppWindowIframe with --gtest_repeat=10 locally.
The result was:
[10/10] PlatformAppBrowserTest.AppWindowIframe (6298 ms)
Before applying this CL, the result was
[10/10] PlatformAppBrowserTest.AppWindowIframe (5773 ms)
This CL may cause a little regression on "chromium/ci/Linux
Tests (dbg)(1)" bot. But if browser_tests too often fails
because of timed out, please revert this CL.

PS1=the reverted CL.

Build overrides in GN

This directory is used to allow different products to customize settings for repos that are DEPS'ed in or shared.

For example: V8 could be built on its own (in a “standalone” configuration), and it could be built as part of Chromium. V8 might define a top-level target, //v8:d8 (a simple executable), that should only be built in the standalone configuration. To figure out whether or not it should be in a standalone configuration, v8 can create a file, build_overrides/v8.gni, that contains a variable, build_standalone_d8 = true. and import it (as import(“//build_overrides/v8.gni”) from its top-level BUILD.gn file.

Chromium, on the other hand, might not need to build d8, and so it would create its own build_overrides/v8.gni file, and in it set build_standalone_d8 = false.

The two files should define the same set of variables, but the values can vary as appropriate to the needs of the two different builds.

The build.gni file provides a way for projects to override defaults for variables used in //build itself (which we want to be shareable between projects).

TODO(crbug.com/588513): Ideally //build_overrides and, in particular, //build_overrides/build.gni should go away completely in favor of some mechanism that can re-use other required files like //.gn, so that we don't have to keep requiring projects to create a bunch of different files to use GN.
