Build with yasm on Win64 as well.

Chromium's doesn't have built-in support for ml64.exe. Seems easier to
just build consistently with Yasm on both Win32 and Win64. (This will
require an equivalent change in Chromium's build, but keep upstream
and downstream builds consistent.)

Also don't set CMAKE_ASM_NASM_COMPILER explicitly; cmake's default
ASM_NASM behavior will search for both nasm or yasm in %PATH%. Leave
it unset so it can be overwritten on the command-line to point to
a particular yasm. Update BUILDING accordingly.

Verified the tests still pass.
