umtool: vendor IBM Plex Mono Bold; `render.fontBold` is the preset's too
IBMPlexMono-Bold.ttf, unmodified from google/fonts ofl/ibmplexmono at
0b58fb37 (the commit S4 took Regular from; Regular there is byte-identical
to the vendored file): 137,784 bytes, sha256 ac27abd6…e0be, blob 17b406d2.
Plex carries the Reserved Font Name "Plex", so it ships whole; OFL.txt
already holds Plex's licence verbatim, and fonts.conf's relative <dir>
picks it up: under FONTCONFIG_FILE, "IBM Plex Mono:bold" now resolves to
it (it resolved to Regular, emboldened, before).
resolveBrandRender sets `fontBold` to it beside `fontRegular`, so
compose-chrome's HyperFrames band sets its bold in the brand's mono
instead of whatever the manifest named. No brand: unchanged, the same
object back.
