[BOLT] Move call probe information to CallSiteInfo
Pseudo probe matching (#100446) needs callee information for call probes.
Embed call probe information (probe id, inline tree node, indirect flag)
into CallSiteInfo. As a consequence:
- Remove call probes from PseudoProbeInfo to avoid duplication, making
it only contain block probes.
- Probe grouping across inline tree nodes becomes more potent + allows
to unambiguously elide block id 1 (common case).
Block mask (blx) encoding becomes a low-ROI optimization and will be
replaced by a more compact encoding leveraging simplified PseudoProbeInfo
in #166680.
The size increase is ~3% for an XL profile (461->475MB). Compact block
probe encoding shrinks it by ~6%.
Test Plan: updated pseudoprobe-decoding-{inline,noinline}.test
