nacl-toolchain: Logically decouple BRP from PA-E

This CL is mainly a no-op, surfacing the GN arg that explicitly disables
BRP when PA-E is disabled. This already happens automatically under the
surface, but we may soon change this.

Context - In preparation for bringing `raw_ptr.h` into the standalone PA
distribution, we are refactoring various GN args and variables. As part
of this series of changes, we will combine the two separate BRP
enablement switches in PA and in `raw_ptr.h`. This is done under the
general assumption that nobody wants to compile support for BRP in one
but not the other - so we might as well tie the support together in the
same logical switch. However, we need to balance two contradictory
cases:

*   In Chromium, most builders not using PA-E are also uninterested in
    using BRP.
*   _Outside Chromium_, embedders may wish to use BRP even without PA-E.

The solution is to logically decouple PA-E usage from BRP usage.
Although this CL is a no-op, it allows us to go under the hood and break
the logical relation in a later CL without disrupting builds.
